So you chose poorly the one time. It often happens to the young and dumb - that’s why you got hired. I had a similar situation where I didn’t get paid either. I took the guy’s semi tractor and trailer and kept it until he paid me.

I’ve done construction work building pole barns over a 3 state area and then I did some road construction running heavy equipment. They always paid overtime after 40 and travel expenses when needed. With road construction the pay could vary depending on if it was for township, county, state, or federal though. The hours almost always 50 to 70 hours a week. Because there was always the next job waiting and a deadline looming to get it done with heavy penalties if you missed them. So OT was never an issue.
