The labor law does not prohibit enterprises from imposing fines on employees who violate the rules, but basically treats them as internal management behaviors of enterprises. Therefore, the enterprise does not need the employee's signature to approve the fine for the illegal employee, but only needs the employee's signature when the enterprise terminates the labor contract with the employee. According to your supplement, it seems that the company deducted your salary by fraud. If the amount is relatively large, I suggest you file a labor arbitration with the local labor and social security bureau on the grounds of "unreasonable deduction of wages". Just put up with it if you don't have much money. In the current financial crisis, workers are in a weak position and can only endure "fighting".
Employee punishment refers to the punishment given by the organization to employees who violate the rules and regulations but do not constitute demotion. Generally, the punishment measures are as follows: (1) The manager requires the employees to have necessary admonishment talks; (2) Warnings can be given orally or in writing, and generally written warnings are used; (3) Disciplinary transfer, that is, transferring employees to unattractive positions, is open, warning and a substantial punishment measure; (4) Temporary suspension, which is a more strategic and severe punishment, can avoid some negative effects that may be brought about by demotion.
