Uber’s Union agreement in the UK doesn’t mean its battles are over The Applam Drivers & Couriers Union (ADCU), made up of original Aslam and Farrar Uber claimants, intends to challenge Uber while it is trying to sue in the National Court. value his business model in London, in a move claiming that it will overturn the Supreme Court’s ruling and allow Uber to avoid a billion-pound tax bill. It would be hard to believe that if Uber had won the Supreme Court case that agreement would have been made at all, says Matthew Taylor, director general of the Royal Society of the Arts and author of the Taylor Review of Modern Working Practices. “Let’s be happy, but it’s realistic. The work that drivers have done and the unions haven’t done, we wouldn’t get here.”
