You may find that your biggest problem will be between your employer and your client. The client may not want to get involved in a dispute over an employee. I have seen this happen quite a number of times and I would reccommend that you negotiate with both parties. If your employer sees that you are going to leave anyway and can be persuaded to not rock the boat (maybe by the client being prepared to offer them more business in the future), then you could have your cake and eat it.
