...41 years ago...before the current unions existed.
Remember the postal strike of 2005? 1993? 1997? 1979? Of course not, because they didn’t happen. I made those up.
We cannot strike.
True. The current USPS employee union, according to the Wiki article, is a combination of previously existing USPS employee unions.
We cannot strike.
If that's true then how did the strike of 1970 happen? Were federal employee strikes legal in 1970?
