What's your payout %? (You are anonymous and you haven't named the firm, so confidentiality shouldn't be an issue.) You take all the losses, but only get a portion of the profit. So far, I haven't seen your calculations reflect that.
So when you asked why you needed to leave, the employee just repeated that you needed to leave and didn't give you a reason. As wrong and stupid as this employee might have been, care to take a guess about what he was thinking?
