workers are set to reject yet another Olympics bonus offer this week, leaving transport bosses scrambling to avoid strikes during the Games, which are now just over four months away.
Almost 150 reps for the RMT will today call on the union to turn down the latest £850 overtime and bonus package.
The reps said the offer unfairly excludes drivers and admin staff.
The RMT executive will now meet this week to decide whether to formally turn down the package, in line with Unite, which rejected it last Wednesday.
Unions have already sealed bonus deals for workers at Network Rail, Virgin Trains, London Overground and Docklands Light Railway.
