Boris Bike Strike: Serco Workers Walk Out
Workers on London's bicycle hire scheme are "solidly supporting" a 48-hour strike over pay and conditions.
Members of the Rail Maritime and Transport (RMT) union employed by Serco on the so-called Boris Bikes have mounted picket lines.
The strike action finishes on Tuesday night although an overtime ban will remain in force.
It comes as the Government announced it will invest more than £100m in making England's roads more cycle friendly.
RMT general secretary Bob Crow said: "With David Cameron announcing investment in cycling, he could start by telling his old school chum Boris Johnson to end the exploitation of his bike scheme workforce.
"This group of workers are rock-solid this morning in their fight for workplace justice and it's about time Boris Johnson got involved in resolving this dispute, rather than treating his bikes as a vanity project."
The union claimed the bike hire scheme was being disrupted by the strike.
But Serco said the service was running as normal.
Serco's contract director for Barclays Cycle Hire, Andrew Hill, said: "Around 70 on-street staff keep the Barclays Cycle Hire scheme moving each day and I am pleased to confirm that despite the strike action, we have been running a full service for customers today. "
Mr Hill also said he was disappointed by the strike action.
"I am still deeply disappointed the RMT have instigated this wholly unnecessary strike given that we have already reached an agreement on the issues the RMT have raised around pay and working pattern changes," he said.
"These were achieved through a comprehensive, thorough and fair consultation with staff that resulted in a pay rise of 2%, which is above the national average and included other improvements to their terms and conditions."
The hire bicycles were dubbed Boris Bikes after being launched by London Mayor Boris Johnson in 2010.
The Barclays cycle routes run from outer London to the centre and are designed to provide "safer, faster and more direct journeys into the city", according to TfL.
