At my UFCW grocery store job I once had a issue with my direct boss, who was in another UFCW Local. I called the Union as the Shop Steward suggested.
They seemed really interested come down like a ton of bricks on the eeeevil boss, until they realized it was another Union member who cause the problem. Suddenly, their was no more problem, despite me not getting paid for the hours I worked. In the end it was the eeevil corporation who stepped up and fixed the issue.
“In the end it was the eeevil corporation who stepped up and fixed the issue.”
There were some tremendously evil corporations in the nineteenth and early twentieth century. But federal and state laws fixed those problems, thus eliminating 99% of the need for unions. That 1% could be resolved any number of ways that do not involve unions. Unions are dinosaurs.
