CA mechanics wages

34% of labor rate? is this correct for a mechanics wage? I got a friend who is a new mechanic and is making 34% of 89.00/hr but only on jobs that make money, ie if he does 8 free lubes a day, he nets like -49 bucks..does this sound right? Hes not even making minimum wage on some days. He is a commissioned employee in CA. but I thought even comm. employees make minimum wage here, like 7.75 hr? He doesnt get an hourly rate on his paycheck, only labor, ie "labor @ 46, Labor @170, Labor @ 0 " etc. Something screwy? New Honda Front brake job with hub R&R, AllData, Chiltons says 8 hours but he's getting paid for 4?
