Legal Question in Employment Law in California

Unless your employer promised you a commission on full retail prices, they are entitled to sell their merchandise for whatever they can get for it, and pay you commission on that amount. In theory you should be making more on increased sales from these promotions, than you would if they stuck to a higher price and sold less items. That is what they are counting on for their profit. If it's not working out that way, you probably should start looking for a new job. Since, if you and they are losing money on the promotions, they won't be in business much longer.

If you are complaining about your commission being computed upon a lower sale price, you are out of luck.
