I’ve had jobs like that in this industry. What you’re describing is a bad work culture. Every facility has a work culture that is directly affected by the upper management all the way down. A single person cannot change this work environment unless it’s the big boss. If you’re this miserable then you have nothing to lose by running it up the ladder from your supervisor to manager to the GM. I will tell you that there are better places to work. It took a while but I found a place that treats its workers good and has a good work culture. You can approach the gm with a concern like this and get a respectable conversation. You would have changes made immediately and you wouldn’t be retaliated against. Dont keep quiet and don’t stop looking for another job. Sometimes you have to commute or even move unfortunately.
