Im an outside sales rep for an offset printing company in ventura california and have been working there for almost a year now. I was hired in with a base pay of 13 hr. plus 10% commissions paid upon customers payment once a month. The owner instituted a incentive plan to try and boost our sales, but with the incentive plan came a plan that penalizes us if we don't make a certain quota. The letter stated that the plan was effective immediately. Which at that point dropped my base pay by 3 dollars an hour with the possibility of being lowered even more. This cant be legal can it?
