Uber is facing yet another controversy after the GMB union launched legal action against it over claims it does not ensure drivers are paid the National Minimum Wage (NMW).

GMB also claims that the controversial taxi-booking service also does not make sure that drivers receive holiday pay.

In the filing, GMB claims that "not only are there breaches of employment law but also that there are serious health and safety issues as currently Uber does not ensure its drivers take rest breaks or work a maximum number of hours per week".

Uber, as much a Marmite company as any other, claims that drivers are 'partners' not 'employees', and are therefore not entitled to usually employee rights.
