Amazon is the latest tech giant to be targeted by a legal challenge in the UK related to gig economy working practices.

The UK’s GMB Union is filing suit on behalf of couriers for three delivery companies used by Amazon — accusing the suppliers of making bogus claims that the delivery drivers were self employed, and thus denying them employment rights such as the national minimum wage and holiday pay.
