When I worked for a titanium coating company I was put on afternoon shift for a week to cover for the normal afternoon guy. The shift was supposed to be 2:30pm to 11:00pm, but one of the furnaces had some broken heating elements. Because of this the furnace still worked, but with only half the elements working the process took longer, and I had to stay until it finished, so I wasn't getting out of there until 2 or 3 each night. Every day I asked my supervisor not to use the furnace, but he insisted that he needed it ( he didn't, there were two others that hadn't been used all week). Wednesday, he questioned me about all the overtime I'd been racking up. I reminded him about the furnace, he told me I was full of shit, and we argued until it was time for him to go home. Thursday when I come in, my supervisor tells me he wants me on day shift for Friday, and he'll take the afternoon so he can fix the furnace. I noticed the broken furnace was already running, so it's going to be another long night. I told him I could take care of it Friday night because I knew how to change the elements and reminded him that I had done it several times before. He said no. For some reason with every job I've had, my immediate supervisor lives in this false reality where I'm the biggest idiot ever and I can't handle tasks beyond the routine things I do every single day. Later that night, something else on the problem furnace breaks (can't describe it, I signed an NDA). It wasn't bad enough that I had to abort the run, but I had to Pause the process for an hour and a half to fix it. I left at 4:30 that night... I had to be back at 6. I had time to go home, shower, change clothes, eat, and relax for half an hour before I had to go back. Friday, when my day should have been over, my supervisor comes in and asked me to stay for a few more hours to keep an eye on things while he fixed the furnace. After yelling and screaming for five minutes straight, I agreed. Luckily, the other guy in the department said he'd do it, so I got to leave.
Speaking of my immediate supervisor always thinking I'm an idiot: For the past six months or so at my current job, there were a handful of things I have been asking my supervisor about doing that kind of need to be done. She either told me they weren't important, or gave me an "I'll get back to you" every time I followed up on it. On Tuesday, she left because of some surgery and won't be back until the end of March. So, I went to my manager about the things I had been mentioning. In two days, I completed all but one of the tasks (with "excellent job!" comments from the manager) and I'm working on the last one, rewriting policies, which is going to take a while. Even if my supervisor had decided to do these things, she wouldn't have trusted me with it. When she gets back, she is not going to be happy...
