How we work

MyMode is our new hybrid-working model, designed to empower our employees to choose a working mode that works for them.

MyMode is composed of 3 working modes: Flex, Office Based and Remote.

Flex (Default)

Tell me more +

Flex is our default working mode, meaning all employees will automatically enrol in this mode and there is no application required to enter this mode. Flex employees will be expected to work from the office at least 4 days per month. Teams will determine whether there are set weekly or monthly in-office days based on their operating rhythms and practices. You will need to work with your manager to determine your in-office schedule for your team.

Office Based

Tell me more +

This option is for employees who are committing to work from the office for a minimum of 4 days per week. As part of taking on the Office Based working mode you will be able to apply for a permanent desk in the office if you need one, but you won’t need to apply to become an Office Based employee.

Remote

Tell me more +

Under the Remote working mode you are able to work anywhere within the country you are employed in. This mode requires around 2- 4 days per year in the office, depending on organisational guidance. You will be able to expense travel if you are asked to attend the office, but not for office attendance by your choice.

*Remote working is not applicable for all roles at Depop, please check with our Talent Team.
