"Labor Law" stipulates: "Units may extend their working hours due to the needs of production and operation after consultation with trade unions and laborers." This provision can be divided into two meanings of "overtime": first, the main body of arranging "overtime" is the employer; Secondly, employees are engaged in production and work during "overtime" time. In the description, the training of employees during the rest time is conducted according to the arrangement of the company, and the training content is related to the production work, which conforms to the characteristics of "overtime". Secondly, "overtime" is to create benefits for employers, that is, to obtain some objective needs on the basis of certain production. The objective needs of employers can be embodied in various forms, such as completing work tasks, creating work performance, improving the quality of employees, and building corporate culture. Even if this objective demand cannot be transformed into economic value in a short time, it should be regarded as "overtime".
