5 Assembly Technician Interview Questions and Answers

Introduction

Junior assembly technicians must follow procedures closely and escalate issues quickly to prevent defects and safety incidents. This question tests attention to detail, adherence to process, and communication with supervisors.

How to answer

• Use a STAR (Situation, Task, Action, Result) structure to keep the answer clear.
• Start by describing the assembly context (product, workstation, shift) and why you were performing that task.
• Explain the exact issue you observed (e.g., incorrect part orientation, damaged component, improper torque) and how you detected it.
• Describe the immediate actions you took: stopping work if necessary, tagging the part, informing your supervisor, and following company escalation or lockout/tagout procedures.
• Mention any follow-up steps you participated in: rework, root-cause checks, updating a checklist or raising an incident report.
• Quantify the outcome if possible (e.g., prevented scrap, avoided downtime, improved inspection pass rate) and note lessons learned.

What not to say

• Claiming you ignored the issue because it seemed minor or to keep production moving.
• Saying you handled it alone without informing a supervisor when escalation was required.
• Giving a vague answer without describing the concrete steps you took.
• Failing to mention adherence to safety procedures or paperwork required by the company.

Example answer

“On a night shift assembling avionics harnesses at a subcontractor for BAE Systems, I noticed that a ribbon cable had been routed under a clip the wrong way, risking chafing. I stopped the line for that workstation, tagged the assembly as ‘hold’, and immediately told the line lead. We removed the part from the batch and reworked the routing following the engineering drawing. I completed an NCR (non-conformance report) with the inspector and we updated the workstation checklist to include a routing verification step. This prevented potential field failures and reduced similar routing mistakes on subsequent shifts.”

Introduction

Technicians are often the first line of defense when production issues arise. This question assesses methodical troubleshooting, use of test/inspection tools, and collaboration with engineering or quality teams.

How to answer

• Outline a systematic troubleshooting approach: gather data, replicate the issue, isolate variables, test hypotheses, and verify fixes.
• Mention specific checks you would perform (e.g., soldering temperature profiles, flux residues, component placement alignment, operator technique, machine calibration).
• Refer to tools and documentation you’d use: multimeter, magnifier/inspection microscope, process control charts, SOPs, IPC standards, reflow profile logs.
• Explain how you’d use sample size and timing to identify patterns (shift, operator, lot number, solder batch).
• Describe escalation steps: when to involve maintenance, process engineers, or quality assurance and how to document findings (e.g., non-conformance reports, production logs).
• State how you would verify the solution (run controlled batches, inspect 100% for a period, update the work instruction) and monitor for recurrence.

What not to say

• Jumping to blame a single cause (e.g., operator error) without data or investigation.
• Skipping documentation or failing to involve maintenance/engineering when needed.
• Relying on guesswork rather than using available tools and standards (e.g., IPC-A-610 for solder acceptability).
• Suggesting permanent fixes without running verification tests.

Example answer

“First, I’d collect data: record when failures occur, which operators, and inspect failed joints under a microscope to classify the defect (cold solder, insufficient wetting, bridging). I’d check the soldering process: verify solder tip condition, iron temperature, flux type and application, and reflow oven profile logs. I’d run a controlled test batch changing one variable at a time (for example, replacing the flux or recalibrating the oven) to see if the defect rate changes. If machine calibration looks suspect, I’d raise a maintenance ticket and work with process engineering to adjust profiles. I’d log all findings in the production report and, after implementing a fix, monitor the line for several shifts with 100% visual inspection to confirm the issue is resolved.”

Introduction

Production environments often face pressure to increase throughput. Employers need junior technicians who can balance productivity with safety and quality and who know how to escalate concerns appropriately.

How to answer

• Acknowledge the need to meet deadlines while emphasizing non-negotiable safety and quality standards.
• Describe steps you’d take to try to increase efficiency safely (e.g., optimise workstation setup, request an extra helper, suggest minor process tweaks within SOPs).
• Explain how you’d track quality metrics during any speed-up to ensure defects do not rise.
• State when and how you would escalate: document risks and discuss with the supervisor, quality engineer or shift manager if asked to bypass procedures.
• Show willingness to help problem-solve (overtime, temporary reallocation) while refusing to compromise on critical safety checks or required inspections.
• Mention UK-specific compliance awareness if relevant (e.g., Health and Safety Executive expectations, company health & safety policy).

What not to say

• Saying you would speed up work by skipping checks or cutting corners.
• Agreeing to any unsafe instruction without question.
• Being confrontational without offering constructive alternatives or escalation.
• Claiming you wouldn’t raise concerns because it’s not your place.

Example answer

“If asked to speed up, I’d first explain that I can try to increase throughput by streamlining my workstation and ensuring tools and parts are pre-staged, or by requesting temporary support from another operator. I would monitor defect rates closely — if quality begins to fall or a supervisor asks me to bypass required inspections, I’d document the request and raise it immediately with the shift manager or quality lead. If the safety of a step was at risk, I’d stop the task and follow the company’s escalation procedure. In a past role supporting assembly for Jaguar Land Rover suppliers, this approach helped us meet a short-term volume spike by adding a temporary quality checkpoint rather than sacrificing inspection steps, keeping delivery on schedule without increasing rework.”

Introduction

Técnicos de montagem devem transformar desenhos e BOMs em produtos físicos com precisão. Esta pergunta verifica leitura de documentação técnica, sequência de operações e atenção a tolerâncias e especificações — habilidades críticas em indústrias brasileiras como aeroespacial (Ex: Embraer), eletroeletrônica ou automotiva.

• Ignorar verificações de qualidade e inspeções dimensionais.
• Assumir que todas as peças caberão perfeitamente sem verificar tolerâncias.
• Focar apenas em velocidade de montagem sem citar segurança ou documentação.

Example answer

“Primeiro eu confirmaria que tenho a versão correta do desenho e do BOM, verificando a revisão. Organizo a estação com as ferramentas (chaves torque, paquímetro) e separo as peças, inspecionando visualmente por danos. Sigo a sequência do desenho: encaixo a carcaça A na base B, aplico o torque especificado nos parafusos M6 com a chave calibrada, verifico folgas com um paquímetro e instalo o subconjunto C usando o gabarito indicado. Faço o teste funcional básico conforme procedimento (giro livre e alinhamento) e completo o checklist no sistema, anexando o número de lote. Se encontrar uma peça fora de especificação, paro a montagem e comunico ao engenheiro responsável para triagem.”

Introduction

Esta pergunta avalia sua abordagem prática a problemas de qualidade no chão de fábrica, comunicação com engenharia/inspeção e respeito pelos procedimentos de controle de não conformidades — muito relevante em fábricas brasileiras com requisitos de qualidade e rastreabilidade.

How to answer

• Use o formato STAR (Situação, Tarefa, Ação, Resultado) para estruturar a resposta.

• Mencione qualquer investigação que participou e medidas corretivas adotadas (re-trabalho, ajuste de processo, alteração no fornecedor).
• Informe resultados mensuráveis quando possível (redução de rejeitos, tempo de parada minimizado) e lições aprendidas.

What not to say

• Dizer que apenas continuou a montagem apesar do defeito.
• Culpar outras equipes sem explicar ações tomadas para resolver.
• Fornecer uma história vaga sem resultados concretos.
• Ignorar a importância de documentar e comunicar a não conformidade.

Example answer

“Em uma linha de montagem de módulos eletrônicos, notei que um lote de gabinetes apresentava furação desalinhada, impedindo o encaixe correto. Parei a montagem daquela série, separei as peças e sinalizei a área. Registrei a não conformidade no sistema com fotos e informei o supervisor e o controle de qualidade. Participamos de uma inspeção e descobrimos que o fornecedor tinha alterado a folga do ferramental. Como ação imediata, reclassificamos o lote como não conforme e realizamos re-trabalho em 20% das peças que ainda podiam ser corrigidas; o resto foi devolvido ao fornecedor. Após a ação, reduzimos a taxa de rejeito daquela característica em 100% para lotes subsequentes. Aprendi a importância de checagens rápidas e de comunicação clara com QA e logística.”

Introduction

Segurança no trabalho e ergonomia são essenciais para técnicos de montagem. Esta pergunta avalia se o candidato equilibra produtividade com segurança, seguindo normas (ex.: NR-6, NR-17 no Brasil) e boas práticas no ambiente industrial.

How to answer

• Explique hábitos pessoais de segurança: uso correto de EPC/EPI, checagem pré-turno de equipamento e organização do posto (5S).
• Descreva como prioriza ergonomia: ajustar altura do banco/mesa, usar ferramentas com empunhadura adequada e pausas para alongamento.
• Mencione como lida com pressão por metas: comunicar riscos ao líder, pedir suporte se processos comprometerem a segurança e sugerir melhorias no fluxo.
• Inclua exemplos de participação em treinamentos e reportes de quase-acidentes ou condições inseguras.
• Mostre consciência das normas brasileiras relevantes (NR-6, NR-12, NR-17) e como aplica essas regras no dia a dia.

What not to say

• Dizer que sacrifica segurança para atingir a produção.
• Afirmar desconhecimento das normas de segurança ou recusar usar EPI.
• Dar respostas genéricas sem exemplos práticos de ergonomia ou comunicação com a liderança.
• Ignorar a necessidade de pausas e rotinas ergonômicas.

Example answer

“Mesmo quando a meta está alta, eu sempre sigo os procedimentos de segurança: verifico EPIs antes de iniciar e mantenho o posto organizado com 5S para evitar tropeços. Ajusto a bancada para trabalhar na altura correta e uso suportes para reduzir esforço repetitivo. Se uma tarefa exigir força excessiva ou improviso, comunico imediatamente ao meu líder para evitar riscos e buscar soluções, como ferramenta adequada ou redistribuição de trabalho. Participo de treinamentos de NR-17 e já sugeri pequenas mudanças em uma estação que reduziram tempo de ciclo e diminuíram queixas de dor nas costas entre os colegas. Priorizar segurança mantém a equipe saudável e sustentavelmente produtiva.”

Introduction

Senior Assembly Technicians must quickly identify root causes of recurring defects to maintain uptime, meet quality standards (e.g., ISO/IPC), and avoid costly rework. This question evaluates problem-solving, technical knowledge, and process-improvement ability in a real production context.

How to answer

• Use the STAR structure: Situation, Task, Action, Result.
• Start by describing the production environment (e.g., type of product, shift, company like Airbus España or Bosch) and the defect symptoms you observed.
• Explain how you gathered data: defect rates, time of occurrence, equipment logs, visual inspections, and operator interviews.
• Describe specific diagnostic steps: measuring tolerances, checking fixtures/jigs, validating torque settings, reviewing process control charts, or running a root-cause analysis (5 Whys, Fishbone).
• Detail the corrective actions you implemented (temporary containment and permanent fixes), including collaboration with engineers or maintenance.
• Quantify the result (reduction in defect rate, downtime saved, cost avoidance) and mention any follow-up actions to prevent recurrence (updated SOPs, training, poka-yoke).

What not to say

• Giving a vague story without measurable outcomes or concrete steps.
• Taking full credit and not acknowledging team members or cross-functional partners.
• Focusing only on blaming operators or materials without investigating tooling or process causes.
• Overlooking safety or quality-system compliance when implementing fixes.

Example answer

“At a manufacturing plant supplying avionics assemblies for Airbus España, we had a recurring faulty connector crimp that caused a 3% rejection rate during final test. I collected defect data by shift and found it correlated with one workcell and the afternoon shift. I inspected the crimp tooling and measured crimp heights against IPC spec; one die showed wear beyond tolerance. I ran a 5 Whys analysis with maintenance and found the preventive-maintenance interval was not reflecting actual cycle counts. I implemented an immediate containment by rotating parts to a secondary die, scheduled tool replacement, and revised the PM schedule based on cycle counts. I also updated the work instruction with a visual gauge check and trained the operators. Within two weeks, rejects dropped from 3% to 0.2%, saving rework hours and improving first-pass yield.”

Introduction

As a senior technician you may be asked to lead shifts or small teams during peak demand. This question assesses leadership, prioritization, communication, and adherence to quality and safety in a pressured environment.

How to answer

• Frame the context: production target, time constraint, and why it was critical (customer delivery, audit, or line recovery).
• Explain how you organized the team: task allocation based on skills, sequencing, and contingency planning.
• Describe how you maintained quality and safety: in-process inspections, checkpoints, PPE and lockout/tagout adherence, and quick escalation paths.
• Highlight communication practices: briefings, progress tracking (visual boards), and coordination with maintenance/engineering/logistics.
• Share measurable outcomes: targets met, quality metrics maintained, and any improvements to prevent future bottlenecks.
• Reflect on leadership lessons and how you coach or motivate technicians under pressure.

What not to say

• Claiming you met the deadline by cutting corners on quality or bypassing safety protocols.
• Solely focusing on the result without explaining team coordination or how quality was preserved.
• Saying you prefer to avoid leading or that you left decisions to others in the crisis.
• Providing no concrete metrics or outcomes.

Example answer

“During a supplier delay, our cell needed to produce 250 additional assemblies within two shifts to meet a delivery window for a major Spanish client. I led a team of six technicians: we held a 10-minute kickoff to assign roles based on experience (critical stations to our most skilled techs), set up a visual Kanban for parts, and scheduled hourly quality checks. I coordinated with maintenance to have spares ready for any tooling issues and ensured operators followed lockout/tagout and torque specs. We met the target with zero safety incidents and maintained a defect rate below our standard 0.5%. Afterward, I documented the temporary workflow and created a short cross-training plan so we could scale faster in future peaks.”

Introduction

Introducing new procedures is common when products evolve. For senior technicians, this requires technical understanding, adherence to traceability standards (batch/serial tracking), good documentation practices, and the ability to train and gain buy-in from technicians—especially relevant in regulated industries in Spain such as aerospace or medical device supply chains.

How to answer

• Start by outlining stakeholder engagement: production, quality, engineering, and documentation/control of records.
• Describe how you'd review design files and regulatory requirements (serial numbers, lot codes, ESD control, torque records).
• Explain pilot testing: create a small run to validate the procedure, capture time-per-unit, and identify failure modes.
• Discuss how you'd develop clear work instructions, checklists, and traceability labels/forms (digital or paper) aligned to company quality systems (ISO 9001, AS9100).
• Detail training and competency verification: hands-on sessions, sign-offs, and initial supervision.
• Mention continuous monitoring after rollout: audits, data collection, and iterative updates based on feedback.

What not to say

• Assuming a new procedure can be rolled out without pilot testing or quality sign-off.
• Neglecting traceability requirements or saying documentation is an afterthought.
• Proposing solutions that ignore regulatory or customer-specific requirements.
• Failing to mention training or how you'll verify technician competence.

Example answer

“If tasked with introducing a variant that needs serial-level traceability for an avionics module, I'd first meet quality and engineering to review the variant drawings and traceability expectations (what must be recorded at each station). I'd run a pilot of 20 units on the line to validate cycle times and identify any tooling or fixture changes. I’d create step-by-step work instructions with photos, specify where the serial number label is applied and scanned into our MES, and add mandatory sign-off checkpoints (visual inspection, torque verification). Training sessions would be hands-on with competency sign-off; during the first production week I'd station myself or a lead near the line to coach. Finally, I'd monitor traceability data and defect trends, then refine the procedure if necessary. This approach ensures compliance, minimizes risk, and builds technician confidence.”

Introduction

Lead Assembly Technicians must rapidly diagnose and contain quality problems to minimize downtime and prevent defective product from reaching customers (e.g., automotive or aerospace suppliers like Magna or Bombardier). This question assesses technical troubleshooting, leadership under pressure, and quality-management skills.

How to answer

• Use the STAR structure (Situation, Task, Action, Result) so your answer is clear and chronological.
• Start by briefly describing the production context (product, shift, team size) and why the quality issue was urgent.
• Explain the diagnostic steps you took (visual inspection, first-article checks, use of gauges or test equipment, review of process data).
• Detail actions to contain the issue (stop-line protocol, quarantine, rework, immediate corrective actions) and how you communicated with production, quality, and engineering.
• Describe any root-cause analysis you initiated (5 Whys, fishbone diagram, SPC data review) and the corrective/preventive measures implemented.
• Quantify the outcome when possible (reduced scrap %, downtime hours saved, prevented customer escapes) and note lessons learned or process changes you instituted.

What not to say

• Taking sole credit and ignoring team contributions—this role requires coordinating across shifts and functions.
• Giving only high-level platitudes like 'I fixed it' without describing concrete steps or tools used.
• Admitting you ignored safety or quality controls to keep production moving.
• Blaming a single person or department without showing evidence from your investigation.

Example answer

“On a night shift at a tier-1 automotive supplier, we discovered an increased paint adhesion failure on one subassembly affecting the final acceptance tests. I immediately stopped the line, quarantined affected batches, and assembled a cross-functional rapid-response team with QC and maintenance. We performed visual and thickness checks on recent batches and ran a quick SPC review that showed a drift in oven temperatures. While maintenance fixed the oven controller, I implemented an interim 100% adhesion check for suspect lots and rerouted unaffected work to continue production. After root-cause analysis we updated the oven calibration SOP and added an hourly temperature log to our control plan. The actions prevented customer escapes, reduced scrap by 80% compared to the initial day, and cut expected downtime by half.”

Introduction

A Lead Assembly Technician is responsible for training, mentoring, and developing shop-floor talent while ensuring consistent output to standards. Interviewers want to see practical approaches to on-the-job training, documentation, and performance measurement.

How to answer

• Describe your structured approach to training (onboarding checklists, shadowing, competency matrices).
• Give examples of specific coaching techniques (step-by-step demonstrations, incremental skill-building, use of work instructions and poka-yoke).
• Explain how you measure competency (skill sign-offs, first-pass yield, time-to-proficiency) and give an example metric.
• Discuss how you adapt training for different learning styles and for shift or language differences (e.g., English/French communications in Canada).
• Mention how you balance training time with production targets and how you get buy-in from supervisors/engineering.

What not to say

• Saying you 'teach on the job' without a clear, repeatable process or documentation.
• Relying solely on verbal instructions and not using visual aids or checklists.
• Ignoring safety/regulatory training or assuming everyone learns at the same pace.
• Claiming you prefer not to spend time on training because it slows production.

Example answer

“I use a competency matrix tied to our SOPs: each new assembler shadows a skilled operator for two full cycles, then performs the task under observation and signs off with me when they meet quality and cycle-time criteria. For one recent hire with limited English, I paired bilingual visual work instructions with photo-based error examples and short video demonstrations. I tracked their time-to-proficiency and first-pass yield; within three weeks they reached the expected 95% first-pass rate. I also schedule weekly 15-minute skill-refresh huddles to reinforce critical points and capture improvement ideas from the team.”

Introduction

This situational question evaluates planning, resource allocation, lean thinking, and safety awareness—key for leads responsible for meeting fluctuating production targets in Canadian manufacturing operations.

How to answer

• Outline immediate, short-term, and medium-term steps you would take.
• Discuss assessing current capacity (cycle times, takt time, bottleneck identification) and where improvements are possible.
• Mention staffing plans: cross-training, shift adjustments, temporary hires, and how you'd maintain quality during ramp-up.
• Talk about process improvements (line balancing, 5S, Kaizen events) and quick wins (reducing non-value-add steps).
• Include how you'd coordinate with maintenance, quality, planning, and health & safety to ensure compliance with CSA/OHS standards.
• Quantify expected gains if possible and explain how you'd monitor KPIs (throughput, first-pass yield, safety incidents).

What not to say

• Suggesting you would push operators to work faster without process changes or safety considerations.
• Ignoring coordination with maintenance/engineering or quality teams.
• Offering only a single tactic (e.g., hire temps) without holistic planning.
• Failing to mention how you'd measure and control quality during the ramp-up.

Example answer

“First, I'd map current takt time and identify bottlenecks using a quick Gemba walk and data from the last month. Short-term, I'd implement 2–3 Kaizen quick wins: eliminate a redundant manual fastening step with a jig to cut cycle time by ~10%, and rebalance station tasks to smooth flow. I'd propose staggered shift cover and cross-train two teams so we can add capacity without sacrificing quality. I'd coordinate with maintenance to ensure preventive checks on critical equipment and with quality to add targeted inspections during the first weeks of the ramp. Medium-term, I'd request an additional FTE or temporary hires if needed and roll out 5S to reduce search time for tools. I would monitor throughput, first-pass yield, and safety incidents daily—aiming to meet the 30% increase while keeping first-pass yield above our 95% target and zero lost-time incidents.”

Introduction

Assembly supervisors must balance productivity, quality, and safety when implementing process changes. This question assesses your leadership, operational decision-making, and ability to manage trade-offs on the shop floor.

How to answer

• Use the STAR structure: Situation, Task, Action, Result to keep your answer clear.
• Start by describing the specific problem or opportunity (e.g., bottleneck at a workstation, high defect rate, overtime costs).
• Explain your role and responsibilities as the supervisor and why the change was needed.
• Detail the actions you took: data collection (cycle times, takt time), consultation with engineers/maintenance/quality, pilot tests, and involvement of operators.
• Highlight how you addressed safety and quality: risk assessments, SOP updates, training, poka-yoke devices, and QC checkpoints.
• Quantify outcomes where possible (e.g., % increase in throughput, % reduction in defects, hours saved, cost savings).
• Mention lessons learned and how you ensured the change was sustained (standard work, visual management, audits).

What not to say

• Focusing only on productivity gains and ignoring quality or safety implications.
• Claiming sole credit while not acknowledging team or cross-functional contributions.
• Providing vague outcomes without metrics or concrete follow-up actions.
• Describing changes implemented without any pilot/testing or operator input.

Example answer

“At Gestamp in Spain, our left-door assembly station was a bottleneck causing weekly overtime. I led a cross-functional improvement: we timed each operation, identified two redundant handoffs, and ran a 2-week pilot where we rearranged tooling and introduced a simple jig to reduce motion. I involved operators in the pilot and ran a quick risk assessment with maintenance and EHS. After training, cycle time dropped 18%, defects related to misalignment fell 30%, and weekly overtime hours decreased by 25%. We documented the new standard work, added a visual board to monitor cycle time, and scheduled monthly audits to ensure sustainability.”

Introduction

Assembly supervisors must prevent defects when new parts or suppliers are introduced. This evaluates your technical knowledge of quality assurance, supplier control, and process validation on the line.

How to answer

• Outline a structured approach: pre-launch planning, incoming inspection, process validation, and feedback loop.
• Describe checks at goods receiving (certificates, dimensional checks, sampling plan) and how you coordinate with quality and purchasing.
• Explain line-side validation steps: trial builds, FMEA or control plan updates, critical characteristics, and required gauges or fixtures.
• Discuss operator training and creation of clear work instructions or visual aids for the new component.
• State how you monitor initial production: increased inspection frequency, SPC charts, and immediate containment actions for any deviations.
• Mention communication with the supplier for non-conformances and continuous improvement actions.

What not to say

• Assuming the supplier part will be fine without any incoming inspection or validation.
• Relying only on quality department without engaging operators and maintenance.
• Skipping documentation or not updating control plans and work instructions.
• Delaying supplier feedback or corrective actions when issues arise.

Example answer

“When SEAT introduced a new harness supplier, I coordinated with purchasing and quality to implement a pre-launch plan: we received a sample batch for dimensional checks and requested measurement reports. On the line, we ran a 3-shift pilot with increased 100% checks on the first 300 units and updated the control plan to include two new critical characteristics. I trained operators on the new routing and added a GO/NO-GO gauge at the workstation. We used SPC to monitor variability; when we detected an intermittent insulation issue, I initiated containment, worked with the supplier to root-cause the crimping process, and implemented corrective actions. This prevented a potential recall and ensured first-time quality during the launch.”

Introduction

Supervisors need to manage performance issues promptly and fairly while supporting employee development. This situational question examines your coaching, conflict resolution, and HR-alignment skills.

How to answer

• Begin with immediate steps: gather objective data (error logs, attendance, cycle times) to define the issue clearly.
• Discuss having a private, respectful conversation to understand root causes (skill gaps, personal issues, unclear instructions, ergonomics).
• Outline a specific improvement plan: targeted training, pairing with an experienced operator, adjusted tasks, and short-term performance targets with review dates.
• Explain how you'd document steps and involve HR if required, following company policy and Spanish labor regulations.
• Describe monitoring and feedback cadence (daily check-ins initially, weekly performance review), and what corrective actions or support you'd offer if no improvement occurs (reassignment, formal warning, performance improvement plan).
• Emphasize maintaining team morale and confidentiality, and focusing on measurable outcomes.

What not to say

• Ignoring the issue or hoping it resolves itself without intervention.
• Publicly criticizing the operator or blaming them without understanding context.
• Skipping documentation or failing to follow HR/legal procedures.
• Taking disciplinary action immediately without attempting coaching or support.

Example answer

“First, I'd review the line reports to quantify the underperformance and speak privately with the operator to understand the cause. If it's a skill gap, I'd arrange targeted retraining and pair them with a high-performing colleague for two weeks, setting clear daily targets. If personal issues are affecting performance, I'd guide them to our HR/employee assistance program while temporarily adjusting non-critical tasks. I'd document all steps and keep HR informed to ensure compliance with company policy in Spain. We'd review progress weekly; if there's no measurable improvement after the agreed period, I'd move to a formal performance improvement plan with HR. Throughout, I'd protect the operator's confidentiality and explain changes to the team in a way that maintains morale.”
