Train drivers across 16 rail operators will refuse to work overtime from 3 July until 8 July which is just short of a strike over the bitter dispute of pay.
Aslef union said their members are to stop non-contractual overtime which will take place during the first week of Wimbledon.
Mick Whelan, Aslef’s general secretary, said, “Once again, we find ourselves with no alternative but to take this action.
“We have continually come to the negotiating table in good faith, seeking to resolve this dispute.
“Sadly, it is clear from the actions of both the train operating companies and the government that they do not want an end to the dispute. Their goals appear to be to continue industrial strife and to do down our industry.
“We don’t want to inconvenience the public. We just want to see our members paid fairly during a cost of living crisis when inflation is running at above 10%, and to not see our terms and conditions taken away.
“It’s time for the government and the companies to think again and look for a resolution.”
