I had the same experience. I hate to say it but honestly, the best job I've had was at an Amazon warehouse. Before that, I was working at a grocery store making about minimum wage and I was living paycheck to paycheck, and meanwhile I was constantly micromanaged and had to put up with customers. At the warehouse, there were a lot of shitty parts but I could afford to live and I was walking around too much for managers to follow me around and bother me too much. It was still soul-crushing and peak season was absolute hell though like I'm not recommending it by any means, I'm just saying that it's not just Amazon that sucks.
