Legal analysis: illegal. In fact, it is illegal to go to work as a full-time worker. Punching in is the company's management system. If there are other punishments, it is an internal problem of the enterprise, so as long as it is not illegal, it should be respected. However, the work-for-relief system is beyond the scope of enterprise autonomy, so it is illegal. Workers have the right to receive remuneration. This is the basic principle of labor law.

Legal basis: Article 3 of the Labor Law of People's Republic of China (PRC) stipulates that workers enjoy the rights of equal employment and occupation selection, remuneration, rest and vacation, occupational safety and health protection, vocational skills training, social insurance and welfare, submission of labor dispute settlement and other labor rights stipulated by law.
