CA mechanics wages

i was a bodyman at a maaco in the bay area i made 35% body labor. i made at least 400.00 a week take home playing around,my best check for the week of hard work was 1240.00 after taxes.but my boss never made me do free work(unless it was my fault redo for pinholes or somthing) your freind should not have to do free work either.that said we didn't have a min wage for comm. employees.only the detail guys lol
