As members of the Rail Maritime and Transport Union voted to strike, the union warned further action would be taken if the row is now resolved. Workers on the Piccadilly Line will walk out for 24 hours on 4 December, but didn't rule out a 48 hour strike at a later date.
RMT general secretary Bob Crow said:
"The overwhelming 88% vote in favour of strike action can leave management in no doubt that the union is not prepared to accept the continuing abuse of individual drivers and negotiated agreements on the Piccadilly Line."
