(Mandatory was about 15 years ago). I was in my early 20's, after hearing all of my older friends gripe about about their student loans (yes they were just as absurd cost wise as they are today). I decided to try community college (strictly only paying for courses and books), ended up being extremely cheaper, therefore allowing me to work as well.
I feel like I actually absorb new information better during evening hours, so I take night classes, then find a job during the day office cleaning and power washing various commercial and residential properties. Scumbag owner of the company decides to not pay me for the entire first month I worked for him. End of the first month, I show up to his house ready to fight, he had some sorry ass excuse, “I thought payroll had been done by my accountant” (if he even had one). It was not. Fuming I motion that his tires are about to be looking very low if he doesn't hand over (more cash than I was told I'd be making per hour) my pay. He pleaded for me not to do anything drastic. He drove to his bank, handed me a couple stacks, told him I quit, and left.
Lesson of the story, intimidation, does indeed work on the owner class as well. Just have to find something they care about more than you, act like you will destroy it, they will pay up.
