My mother worked almost every day of WWII at Hughes Tool milling out oil drilling bits. She worked seven days per week and most holidays; she worked double shifts.
The union called a strike which she ignored. She was pelted by rocks crossing the picket line. She yelled back at them, “Don’t you fools realize there’s a war on?”
God bless Mom. She never learned to drive a car, but she could run a milling machine for 16 hours straight!
Good for your Mom. My Mother also crossed a picket line, but it was a very small clerical union, nothing to do with war.
