I mean... I can buy this to a point. But for me personally, there are lines. And there are things I'm just not going to do. Period.
I know it's un-trendy to talk about anything being "beneath you", and I'm not sure that's the wording I would use, but there are simply things that I don't consider being in my wheelhouse and that if you ask me to do, I'm going to say "no". Then you can decide if you want to fire me or not.
Case in point: I used to be a parts counter clerk at Advance Auto Parts. We got a new manager and one day he comes in and asks me to go outside and sweep the parking lot. I said "no" and he tells me to do it or I'm fired. So I rip off my Advance Auto Parts shirt, throw it in his face, say "fuck you" and walk out. 30+ years later I feel absolutely no regret about that. I didn't apologize then and I won't now.
There's more to my life than a job and I can find another way to pay the bills. I don't have to take their bullshit.
