Im an hourly sales employee where my compensation is hourly+Commission+ OT + Bonus if applicable. Recently I had a dispute and legal department had to be involved settling at 10% for any deal moving forward. Weeks later my direct supervisor told me that he was able to motivate our corporate to pay me 12.5% instead and also obtain a written confirmation from corporate. They paid my twice at 12.5% and now legal is changing my % back to 10% saying it was amistake or typo... is this correct or even legal?
