TUC general secretary Frances O'Grady said:
Employment tribunal fees have been a huge victory for Britain's worst bosses.
By charging up-front fees for harassment and abuse claims the Government has made it easier for bad employers to get away with the most appalling behaviour.
Tribunal fees are part of a wider campaign to get rid of workers' basic rights. The consequence has been to price low-paid and vulnerable people out of justice.
