The report says that strikes cost the UK economy £48 million pounds per day of industrial action - adding up to £1bn between 2005 and 2009.
Richard Tracey, GLA Conservative Spokesmanfor Transport, said:
“Seven in ten rail journeys in the UK begin or end in the capital.
"For too long London’s Tube unions have been holding the travelling public hostage, demanding ever greater pay deals and calling strikes at the drop of a hat.
"We need to urgently readdress this imbalance.
"Our research shows six in ten Londoners feel it is too easy for Underground staff to go on strike. Almost half would favour a ban on industrial action.
"Banning strikes tied to a wider package of compulsory arbitration will protect commuters and the UK’s economy.
"It will also ensure Tube drivers and staff do get a fair hearing from London Underground management when seeking to secure wage and benefit improvements.
"And there is no reason why we cannot curb strikes and implement compulsory settlements on other forms of transport in London and across the UK.”
