Andy, Sounds a load of shit to me mate!!! Its pathetic at just the fact she has got a verbal for not selling enough shoe care!!!! If they are so bothered about flogging more then who ever is incharge should be out there flogging it them selves and then see how many they sell!! In terms of if they can do it or not is a different matter!! Has she got a contract with them? Does it say how much shoe care she had to sell? if not...did they give it to her in writting/amend her contract to say you have to sell X amount more of shoe care? If not mate they havent a leg to stand on!!! Personally I would tell your miss's to stick it right up ther jacksy, and get another job (appreciate its easier said than done) But as a straight forward answer...No they cant. It HAS to be in writting of what they are expecting from her!! If it was then unfortunatly they can do what they want. (doesnt mean to say you cant make there life difficult in the process....just go for bullying in the work placement!!! works a treat!!)

Good luck
