Dominic Raab, Tory MP for Esher and Walton, introduced a 10-minute rule Bill earlier this week, which would require a strike to be backed by a majority of trade union members.

It’s a timely reminder, given that London Underground has balloted for strike action. Again.

The cost of Tube strikes to the Capital is around £50m each day, not to mention the disruption inflicted upon passengers who must find alternative means of travel.

The right to strike is an essential element of democracy that allows unions to protest unfair treatment and negotiate terms to protect their members.

Yet this can be misused when union members can instigate strikes with a minimum of followers. Bob Crow, leader of the RTM, has the support of only 39% of the union and is still authorised to strike.

Raab’s new law could mean that the strike has to be properly supported by the whole of the union, determining that is the appropriate action.

That can only be right.
