There's a difference between "taking shit" and "kissing ass". You're welcome to believe them the same, but understand that the consequences impact your employ-ability. There's a whole set of skills about managing workplace boundaries. Its not a binary of "taking shit" all-or-nothing. Its picking your battles and choosing to refuse to do things that would harm you physically or mentally, or those things that are simply annoying or hits to your pride. If you have to maintain your "not taking shit" image because of ego, I can tell you that will likely be very costly to you.

I can tell you from far up the chain (just because I'm older and have been doing this longer) there are zero jobs where you can avoid "taking shit". It comes in different forms. Right now you're talking about your direct manager or supervisor it sounds like. The higher up you go it comes from even higher bosses, government agencies, vendors you're forced to deal with, regulatory auditors, insurance companies, then, paradoxically, employees you manage.

There is no "taking shit"-free job. That only comes when you exit the workforce...which is one of my goals I'm working is to speedrun to earn enough money to do that before age 65 or 67 assuming you've saved appropriate to allow you to do that.
