Is the eight-hour work system reasonable?

First of all, the eight-hour work system is legal.

Legal basis:

Article 36 of the Labor Law of People's Republic of China (PRC): The state practices a working hour system in which the daily working hours of laborers do not exceed eight hours and the average weekly working hours do not exceed forty-four hours.

Article 37 The employing unit shall, in accordance with the working hours system stipulated in Article 36 of this Law, reasonably determine the labor quota and piecework remuneration standard for the workers who carry out piecework.

Article 38 The employing unit shall ensure that workers have at least one day off every week.

Article 39 If an enterprise is unable to implement the provisions of Articles 36 and 38 of this Law due to its production characteristics, it may take other measures for work and rest with the approval of the labor administrative department.

Secondly, I think it is unreasonable.

The eight-hour working day is a "traditional invention".

Perhaps in a certain period, the eight-hour working system of a certain process in a certain industry has the highest cost performance ratio (too long working hours are easy to make mistakes, too short working hours occupy the station+it is difficult to become a skilled worker quickly), but it does not mean that the eight-hour working system of other processes in other industries is reasonable (even for people, some people may not be able to do it in six hours, and some people are full of energy in twelve hours).

In addition, the eight-hour working system is not advanced but backward, which is a one-size-fits-all approach and lacks refined management.
