JT provide colleagues with an opportunity to embrace flexibility to work the hours that suit them in a location of their choice - office, home or further afield under our Hybrid Working guidelines.

Through our hybrid working initiative we have diversified the ways in which we recruit, which also means that we are now able to support posts in major global locations. The benefits that are listed above are an example of those that we provide in our key locations, if you are applying from outside of these areas, please note that your compensation package might look a little different.

Our main priority is colleague wellbeing, and we hope this offers greater opportunity for a work life balance. We aim to offer this approach to all colleagues across the business, but we recognise that there are certain roles that will need to work in a specific way due to their nature, such as our colleagues working in engineering, our contact centres and our retail outlets. We are actively working with our management teams to increase flexibility wherever we can.
