Uber lost an appeal against a landmark 2016 ruling that the ride-hailing firm should treat its U.K. drivers as workers entitled to benefits like a minimum wage and holiday pay.

A judge at the U.K.‘s Court of Appeal, the second-highest court in the land, ruled in favor of Uber drivers James Farrar and Yaseen Aslam, who in 2016 argued at an employment tribunal that they were employees working for the company, rather than self-employed.
