What you want to ask is, are all employees members of trade unions? Not necessarily. According to the enquiry of China Travel Service. Com, employees in enterprises are not necessarily trade union members, and trade unions in enterprises need employees to apply for membership. Workers who require membership submit a written (oral) application to their trade union or trade union group, fill in the Application Form for Membership of the All-China Federation of Trade Unions and the Registration Form for Trade Union Members, and submit it to the trade union group for discussion. According to Article 3 of the Labor Law of People's Republic of China (PRC), workers enjoy equal employment and occupation selection, remuneration, rest and vacation, labor safety and health protection, vocational skills training, social insurance and welfare, submission of labor disputes and other labor rights stipulated by law. Laborers should complete labor tasks, improve their professional skills, implement labor safety and health laws and regulations, and observe labor discipline and professional ethics.
