The bill, which would tighten rules on strike ballots in Britain, passed its first major parliamentary hurdle on Monday when MPs passed it by 33 votes at the second reading stage.
Unite leader Len McCluskey told the conference in Brighton that his union will oppose the bill using “any means necessary” to defend the democratic rights and freedoms of workers.
He said: “This Prime Minister seeks to paint the millions of trade unionists and their families as ‘the enemy within’, with a Tory party drunk on class prejudice, intent on destroying this movement as a force in British life.”
If made law, the bill would introduce a new 50% threshold on participation in strike ballots, as well as changes requiring picketers to give their names to police.
