BRITS face the biggest nationwide shutdown in a century after the militant RMT boss refused to rule out a general strike.
Leftie agitator Mick Lynch threatened to plot “coordinated” walkouts with other unions to cause maximum misery.
A general strike could see workers across industries including aviation, schools and health down tools.
Mr Lynch is already orchestrating three days of rail strikes later this month to bring the country’s trains to a standstill.
And today he warned of even more chaos by hinting he could scheme with other union leaders to unleash mammoth disruption.
Asked about organising a mass walkout, Mr Lynch told LBC it would make sense for workers to leverage their power”.

He said: “We’re ahead of the band in that sense, because we’ve got direct issues.
“But if you look at what’s happened in the aviation industry where they cut 1000s and 1000s of jobs, and now they can’t operate the airport to the airlines…So something needs to be done about this.”
