Tory proposals in the Trade Union Bill to impose new industrial action ballot thresholds for turnout (50%) and support (in 'essential services' 40% of all balloted) 'would make almost all strikes illegal, particularly in large and dispersed workforces where postal ballots rarely achieve this' writes Michael Meacher MP. http://www.leftfutures.org/2015/06/tory-trade-union-bill-is-an-attack-on-a-fundamental-human-right/
The proposals if implemented (without a return to workplace balloting) will severely undermine national bargaining with union's unable to exert leverage in future negotiations on pay, pensions etc.
The Trade Union Bill is a political attack on trade union rights as vicious as any law enacted during the Thatcher era. A major campaign inside and outside of Parliament is required to resist this draconian legislation.
