Many London tube workers refused to work on health and safety grounds during the firefighters’ strike on Saturday, severely affecting the running of London Underground.
The action, by workers in the Aslef and RMT unions, particularly hit the Jubilee and Piccadilly lines.
Both unions issued advice to their members about their right to refuse to work during the FBU’s strike.
And tube workers are set to strike for a further 24 hours from 7pm next Tuesday.
Members of the RMT, along with TSSA union members, are fighting job and safety cuts on the tube.
“The refusal to work showed a glimpse of what is possible if we coordinate the action in both our disputes,” said one tube worker.
“It was a launchpad for further action,” they added.
Activists in the Trouble Down The Line rank and file group are arguing to step up the walkouts during the next round of fire strikes, and to extend the length of the tube strikes.
Other groups of workers should follow their excellent example.
