Whenever I got 'attitude' from frontline employees of businesses who were tasked with COVID enforcement I always pushed back. Tit for Tat. Yeah, it might not be fair to the worker. But if none of them threatened to quit then their employers would never modify the stupid policies.
You had to be careful about it. Calibrate your response so as not to draw a law enforcement response. You'd never argue with a flight attendant. But the office lady at the doctors office got cranky one morning after the COVID thing was finally lifting this spring and I nailed her with a sharp verbal response about cloth masks 'not working' and that her rules were complete BS. She replied that they "weren't her rules" but I countered that she appeared to be having "a bit too much fun enforcing them" for her to deflect all responsibility.
I disagree with your approach.
Let me explain.
One of the goals of the “bad guys” is to get us to angry with each other, alienated from each other, separated from each other—so we can’t resist them.
Once you see that you realize that your job is to either gain new allies—or if that is not possible—then do nothing.
You were not going to convert these people to your point of view—so you created heat, not light.
What you want is to stay on good terms with as many people as possible so that you can gently try to get them to join the “good guys”—when they appear ready.
