The company says the new model could create more than 1,000 jobs by March.
Initially due to be applied to couriers in central London before being rolled out to other cities next year, the new terms will see the removal of the current pay-per job model and entitle all 1,500 of Just Eat's UK staff to minimum or living wage; pension contributions; holiday pay; sick pay; and maternity or paternity pay.
Roles will be split between a mixture of full-time, part-time and zero hours.
Staff will be given the option to opt out of the new system and continue to work as independent contractors if they wish to do so, but the changes are said to increase job security and improve the working conditions for those in the so-called gig economy.
The business will also provide e-bikes and e-mopeds, as well as branded clothing and equipment to couriers for the launch of the initiative.
“As the market leader in online food delivery, we believe it is our responsibility to offer couriers a wide range of working options and benefits,” says Andrew Kenny, Just Eat UK managing director.
“From our experience in other European markets, we know many couriers value the benefits our new model offers and with the use of electric vehicles, this launch will also help us build a sustainable future for food delivery in the UK.”
