Uber is forcing drivers in Seattle to listen to anti-union propaganda
It should be compulsory for everyone to be a member of a union as the HR staff at Uber have recently shown.

In the UK there is ACAS as well but being a member of a union is important for all sorts of reasons; fair pay and better working conditions are just two.
