Drivers on the Jubilee line are to vote on strike action in a dispute over working conditions and alleged bullying, the Tube union RMT announced today.

The ballot will be in reference to apparent unfair treatment of drivers in disciplinaries, the removal of some benefits, a lack of managerial support, and the “disgusting” state of some facilities, the union said.

RMT General Secretary Bob Crow said: “RMT will not sit back and allow the wilful misuse of procedures on any part of the Tube network as a means of bullying and intimidating our members.

“That is exactly what is happening at the moment to drivers working out of Greenwich and Stratford on the Jubilee Line and we are demanding that the practice be called to an immediate halt.

“Our members are also sick of the gradual decline in working conditions and facilities which have been allowed to degenerate into a disgusting state and which appears to be another petty and vindictive way of sniping at union members on the Jubilee Line.

He added: “RMT will begin immediate preparations for a ballot for industrial action and no one should underestimate the anger amongst Jubilee Line staff at the moment. RMT remains available for talks aimed at resolving this dispute.”

John Doyle, Jubilee line general manager for London Underground, said: “The unions have informed us that they are in dispute with us over what they perceive as a breakdown in industrial relations.

“We are keen to understand their concerns and so will be meeting with the union later this week to discuss these issues in greater detail.”
