The Trade Union Law of China (《中华人民共和国工会法》), amended most recently in December 2021 (effective January 2022), supports workers' freedom of association:

- All employees have the right to join and organise trade unions.
- Enterprises with 25 or more union members should establish a grassroots union committee.
- Collective contracts on wages and working conditions may be concluded through collective consultation.
- Union funds are contributed at 2% of total payroll (included in costs).

Freedom of association and collective bargaining are core modules in SA8000 and SMETA audits. CSER Solutions helps factories understand union structures, worker-representation mechanisms and grievance channels that satisfy international standards.
