TUBE services on London Underground’s Bakerloo line were hit by strike action yesterday as workers walked out over “unworkable timetable changes.”

Rail union RMT said that the timetable changes put drivers under “intolerable levels of personal stress.”

The union accused bosses at Transport for London (TfL) and London Mayor Sadiq Khan of choosing “point-blank to ignore union warnings on the risk to passengers and staff alike” caused by the changes.

They had also “snubbed an opportunity to reach a settlement that puts safety first,” RMT said.

A ballot for action by drivers resulted in a 95 per cent vote to strike.

The strike began at noon and will last for 24 hours. A second 24-hour stoppage will begin at noon on Sunday.

RMT general secretary Mick Cash said: “RMT is angry and frustrated that hard work by our reps aimed at reaching a negotiated solution to this dispute has been wasted as the company have played us along and failed to make any kind of serious progress.

“Their behaviour has been nothing short of outrageous as they ignore clear union warnings on the safety of passengers and staff alike.

“Drivers voted overwhelmingly for action in this dispute which is all about the management imposing timetable changes on the Bakerloo line without any serious recognition of the stress impact on the operators expected to implement them.

“The bottom line is that you cannot place intolerable stress and pressure on tube drivers that impacts on their safety-critical role, and that is what this dispute is all about.”
