If you worked for me back in the day and no showed for work or called in sick, and then were seen “protesting” outside the store you earned a fast track ticket to the unemployment line. There were too many employees who wanted to work and wanted the hours for me to hold on to deadwood, but then 99% of these “strikers” are union paid outsiders.
I remember when I graduated from Tech school in 1983 and one of my classmates was leaving his job at McDonalds and offered to “get you in” to a couple of us. Times were really bad in Pittsburgh at that time and the offer was not taken lightly.
