The RMT union says it has reached agreement with London Underground bosses in its long-running row over jobs, pay and conditions.
Staff will receive an Olympic bonus of “up to £850” which LU says is “subject to attendance, customer satisfaction scores and working flexibly for defined periods in order to deliver a successful Games.”
LU is also allowing Tube drivers to work overtime during the Olympics, something which is not usually permitted.
Members of the Aslef and Unite unions have already agreed the same deal with LU while the TSSA union has agreed to it “in principle”.
RMT General Secretary Bob Crow said: “After months of hard work by our negotiators we have been able to come to an agreement that both protects the contractual rights and existing agreements of our members and rewards them in recognition of what we all know will be the biggest transport challenge ever faced by this city.”
The union says it “remains deeply concerned at the staffing levels planned by LU and the use of untrained volunteers at a time when safety and security will be absolutely paramount.”
Howard Collins, LU Chief Operating Officer, said: “I am pleased that we have now got agreement from all four unions on our proposals for how we can fairly reward staff over the London 2012 Games.
“I know our staff are keen to play their part in the Games and, now that we have agreement across the board, we can all look forward to focusing on supporting a fantastic summer of sport and cultural events in London.”
