Our people are at the heart of the business and we have a culture of recognition and reward – both through regular appraisals but also annual Extra Mile Awards where we celebrate those who have gone that extra mile in their role. 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. Not only do we enjoy monthly Treats on Ten (on the tenth of each month!) but employees also 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.

Other benefits that Ten offer, specific to the UK office, range between an employer-contributory company pension (with a scheme that allows full decision making about what investments are made, levels of risk, ethical funds etc), all the way through to various discounts on both travel and entertainment events (the latter is of course available regardless of location). There are also lots of social events throughout the year (including drinks on the last Friday of the month) as well as a break-out room where employees can relax (or, if they wish, play one of the numerous games we provide!) whilst enjoying our latest fruit drop or “Breakfast on Ten”.

We also offer season ticket loans, access to childcare voucher and cycle schemes and, one of our more popular perks, working holiday opportunities with the ability to work from any of our 20+ offices without taking annual leave.
