You have the right not to sign, but you know exactly what will happen. The fine system is formulated by the company and is a part of the company's rules and regulations. It is unreasonable, but once it happens to you, you can't accept it. It can only be settled through labor arbitration. You can suggest that if you don't sign it at first, you may be asked to leave your job, but signing it is an unreasonable treaty, depending on what you think. You win if you don't sign.
