The Conservative report included an opinion poll, which found that 48% of Londoners support some kind of ban on strike action.
A complete ban - which would see workers sacked for withdrawing their labour - was backed by 16%.
Another 15% supported the introduction of rules used on the New York subway, which bansstrike action but give unions a right to binding arbitration. And a further 16% favoured pendulum arbitration in which a judge cannot compromise but has to choose between either the employers or unions position.
The survey also found that:
- 59% think it is too easy for Tube workers to go on strike.
- Only 14% of Londoners back the status quo on strike law and 6% want to make it easier to strike.
