Benefits

Our people are at the heart of the business and we have a culture of recognition and reward. We also encourage all our staff to incorporate their aspirations and interests into their career at Ten and we are there every step of the way in supporting development.

All our employees also enjoy a range of benefits regardless of where they are based. Employees get 3 extra days of annual leave in their third year and an extra month of every 5 years.

In line with these milestone lengths of service, we also operate a Ten Loyalty Reward program – this is a bonus (although we prefer to refer to this as ‘extra spending money’) that is awarded once these milestones are reached. The thinking behind the program is that not only does it recognise and reward commitment and loyalty to the business, but it can also be used to fund the adventures to be had during sabbaticals – this is the main intention and driving force behind the program. We want to give our people extra spending money so that they can truly enjoy their sabbaticals.

One of our more popular perks, working holiday* opportunities with the ability to work from any of our 20+ offices without taking annual leave.

Our employees also enjoy a dedicated concierge portal comprising of travel, dining, events and other luxury experiences to choose from.
