CA mechanics wages

The only commission job I had was paid commission or minimum wage, which ever was more. So on a bad week you would get paid $8 an hour or what ever it was at the time.

Most shops pay flat rate which means you get paid for the hours the book calls for.
So if the job calls for 4hrs you get paid 4hr even if it takes you 6. but if you do the job in 2hrs you still get paid the 4hrs.
