High School. I went to work in automotive parts assemblies. Brakes mostly and some transmission parts. High school didn't really help. Not having a degree did stop me from getting promoted. It wasn't something I wanted. I was a supervisor for about 20 years. Stepped down to PM maintenance. Wound up making more money since hourly and overtime. I was also trained in the actual job. I wound up training engineers on the machines because I knew how they worked and how to fix. Engineers, at least at my work, were pretty useless. Not knocking engineers but they didn't seem interested in learning. To me a degree was worthless unless I wanted to be promoted.
