They paid me the draw every month and I am leaving because I did not earn any commission. It is too hard. agreement doesn't say anything about overtime or minimum wage.
It doesn't have to. The law says you must be paid at least minimum wage for every hour you work and OT pay for every hour over 40 that you work in any given week.
Regarding being sued for the draw, you really really really need to run this agreement by an attorney.
