Assuming your friend is in an "at will" employment situation, unless there is a contract stipulating her duties/responsibilities and the sale of this new product is outside the scope those duties/responsibilities, there may be little that she can do. The reasonableness of the employer's request is really dependent on the value of the product she will be selling and the forecasted volume of sales. For example, if she was selling $25 widgets with a quota of $250,000 and the company now requires her to sell $100 widgets with a quota of $1,000,000 there really are no grounds to find the employer at fault. If the facts suggest that the corporation is placing an unreasonable requirement on your friend simply to later provide grounds to terminate her, then she could contact the State labor board and request that they review the matter.
