Some companies are more evil than others.

Some will lie repeatedly to even avoid paying out a settlement.

In America you have no rights, your lucky if you get paid on time. Even then the actual process to get your back owed wages usually isn't worth the effort.

I worked for a clown once who waited 30 days to tell me he only pays every 60 days.

A friend of mine wasted a full week training, and the employer decided they didn't need him and didn't pay for the training.

If you DARE try and go the legal route you'll find you can basically beg for a settlement, but your employer can just say no.

Going to court isn't going to be worth it since the system is heavily stacked against you.

Actually not paying earned wages is one of the few things that has a lot of teeth around it. Federal rules typically award back pay and an equal amount as liquidated damages, plus attorney's fees and court costs, and states may add penalties of their own.
