So I’ve been training as a machinist for about 3 months and lately my boss who I thought was my friend (my mistake) put a list up in full view for everyone to see of mistakes I have made as a trainee. He told me he doesn’t know how many mistakes it will take but he said that when he feels too many have been reached that he will fire me. The mistakes that are listed aren’t serious like crashing the machine, breaking a part, or anything along those lines. But I’m not sure how to approach this situation since it seems like he’s actively looking for things to put on the list. Should I ask him to take it down or start job hunting? I’m not even sure if it’s something that can legally be done in a corporate setting. Any advice is appreciated thanks everyone.
