Memo tells ministers to disregard minimum service levels rules, as part of reforms to reorder industrial relations

The government will begin the task of rolling back years of anti-trade union laws within days, the Observer can reveal, as ministers are ordered to ignore a key measure passed by the Tories as part of a wider “reset” of industrial relations in Britain.

As a first step, departments will be told effectively to ignore a law passed last year designed to force workers across a series of industries to provide a minimum level of service during strikes. The legislation – described as a “pointless gimmick” by ministers – paved the way to severely curtail the rights of border security, ambulance services, fire and rescue, teachers and rail services to take industrial action.
