Maintenance workers on London Underground have voted to strike over claims of a breakdown in industrial relations.

Members of the Rail, Maritime and Transport (RMT) union backed walkouts by two to one and by almost nine to one for other forms of industrial action.

General secretary Mick Cash said: “The level of flagrant abuse and ignorance of long-standing policies and procedures is unacceptable.

“The anger among RMT fleet grades members is clear following this overwhelming mandate for strike action and action short of a strike.

“The ballot result will now be considered by RMT's executive and it is down to London Underground to start taking this list of grievances seriously, to stop trying to impose fundamental changes to agreed policies and working conditions and to halt the bullying and harassment of our reps.

“RMT remains available for serious talks.”

The ballot result will now be considered by RMT's executive.

A Transport for London spokesperson said: "We urge the RMT leadership to work with us constructively on the issues it has raised rather than threaten unnecessary industrial action."
