The RMT Union has announced that staff on the Windrush Line are to carry out strike action in February.

Workers who are employed by Cleshar CS Ltd have been offered a 1.5% pay rise.

The union says that the dispute also involved problems with overtime and annual leave pay, as well as other terms and conditions.

Strike action will take place on the 26th February, 26th March and 23 April 2026.

Without staff who work on signals and telecoms, trains will not be able to run.

“Our members have been insulted with such a derisory offer and have no choice but to take strike action.

“This company is highly profitable and can afford a decent offer for these safety-critical workers.

“Strike action would be disruptive and our members do not want to inconvenience passengers.

“But the company has a duty to pay our people properly and we will continue our campaign until we reach a negotiated settlement.”

RMT general secretary Eddie Dempsey
