Our company (private enterprise) has recently introduced a reward and punishment system, which is simply an unequal treaty. Is there any legal advantage in this? What if you sign it?

Rules and regulations that conflict with the spirit of national laws and relevant regulations are invalid, and some conflicts are invalid.

I heard that the rules and regulations of some enterprises only stipulate employees' obligations, but seldom mention employees' rights. Your company's rules and regulations should be typical of this kind. Even if there is a labor dispute, the system is likely to be invalidated by the court.

But if his employees' rights and obligations are relatively equal, it will be effective.

First, you need to sign, which is a way to publicize the company's rules and regulations;

If it is legal, it has legal effect. If it is the invalid clause mentioned above, even if you sign it, it has no legal effect. If there is a labor dispute in the future, you can claim compensation for the withheld money.
