Probably not quite what your looking for, but I literally just came across this article about a potential general strike in 4 years:
“UAW president Shawn Fain on May Day calls on unions to prepare for strike in 2028”
“We are fully preparing to strike on May Day 2028,” Shawn Fain wrote in a proposal on May Day, or International Workers Day.
Fain said it is the only way workers can “win universal healthcare and the right to retire with dignity.”
[In an op-ed (https://inthesetimes.com/article/may-day-2028-general-strike-working-class) for progressive publication In These Times, Fain said the union’s recent auto contracts were all aligned to expire on April 30, 2028. He called on other unions to do the same as way to mass power to “reshape the economy into one that works for the benefit of everyone.”
“They want us to believe that corporate bosses gave workers decent wages, benefits and safer working conditions out of the goodness of their hearts. That justice and equality for people of color, for immigrants, for women and for queer communities were gifts benevolently handed down from above,” Fain wrote.
“But we know the truth. Every law passed, every union formed and contract won—every improvement made at the workplace—has been won through the tireless sacrifice of the working class.”
I haven’t looked at the statistical data on this myself, but there’s something to be said for survivorship bias.
