Is it legal for the company to implement the 12 hour working system?

Legal analysis: law. Unit rest 12 hour does not violate the labor law, as long as the employer pays the laborer's labor remuneration and overtime pay in full according to the provisions of the labor law. The implementation of such working hours does not require approval unless the company implements a comprehensive working hour system or an irregular working hour system. Only these two working hours need to be approved by the local labor department, and the company can implement such a working hour system after approval.

Legal basis: Under any of the circumstances stipulated in Article 44 of the Labor Law of People's Republic of China (PRC), the employing unit shall pay wages higher than the normal working hours of the workers according to the following standards:

(1) If the laborer is arranged to work longer hours, he shall be paid no less than 150% of the salary;

(2) If workers are arranged to work on rest days but cannot be arranged to take compensatory time off, they shall be paid no less than 200% of their wages.

(3) If workers are arranged to work on legal holidays, they shall be paid no less than 300% of their wages.
