I started a new job at a machine shop. The owner makes axle spindles for semi trucks and trailers. It’s a CNC machine shop. A lot of new equipment that cost over $500,000, computers, robots etc…He hired me with no experience. The interview stated I would be doing dispatch to supply his technicians on the road with parts they need to fix the trucks with slow introduction into the machines. Now that’s not the case, he told me yesterday that won’t be my job. It’s me learning how to CNC. However this dude is very smart and his whole life is this company he’s 60, no wife or kids and he constantly reminds me how careful I have to be because this part is 5,000 and that button is 600 and this machine will crash if it’s not the perfect measurement. But I have NEVER done any of this shit before. It’s complicated and people go to school for this skilled trade. I’ve made some mistakes. He will show me something once and expect me to get it and talk to me like I’m stupid if I don’t. Or I’ll trying to talk out loud through a certain process with him and he has no patience for it. He makes me extremely nervous to work next to him because of me constantly worrying about messing up. I’m on edge all day and I don’t like being talked to like that. I’m 30 years old and I’m finding out he can’t keep people. No grown man is going to be talked to like that. Now I’m stuck. I left a job because of the pay for this one and it’s closer to home. I don’t know if I need to talk to him and explain I can’t learn like this and something needs to change or just find something else but like many other Americans I don’t have money saved up to quit. I’m stressed out. I want to learn and I’m willing but damn, the condescending tone and the nervousness I feel is making me hate this place. I don’t know what to do.
