The rail union Aslef is to ballot more than 2,000 London Underground members to see if they want to cause more misery and discomfort to London passengers again next month by walking out on their jobs.

The union plan on coordinating with the RMT who have already staged two strikes over alleged safety and rota issues.

The reason behind the proposed action? There has been a "serious breakdown in industrial relations and trust" with management.

Andy Reed of Aslef said industrial relations varied from hostility to anarchy.

He said: "Ken Livingstone wrote to the union in November 2002 promising a review of London Underground Limited's harassment procedure. In over two years, LUL has failed to progress this.

"Discipline appeals appear to be pointless exercises rather than serious re-considerations.

"Representatives are not allowed time off for union duties. Transfer agreements are regularly ignored. We cannot allow this position to continue."

Talk is cheap - better to walk and cause chaos it seems.
