Legal analysis: 1. Employers provide special training fees. According to the national regulations, the employer must withdraw the training fee according to a certain proportion of the total wages of the unit for the vocational training of the workers, and the use of this part of the training fee cannot be used as a condition for agreeing the service period with the workers. It can only be a special training fee, which exceeds the training funds stipulated by the state. 2. Workers receive professional and technical training. Including professional knowledge and skills, such as introducing a production line from abroad, there must be people who can operate it. To this end, workers are sent abroad for training.

Legal basis: Article 4 of the Labor Contract Law of People's Republic of China (PRC), the employing unit shall establish and improve the labor rules and regulations in accordance with the law, so as to guarantee the laborers to enjoy their labor rights and perform their labor obligations.

In the process of implementing rules and regulations and major issues, trade unions or employees have the right to propose to the employer and revise and improve them through consultation.
