Disputes often occur between corporations and labor unions over working conditions or unfair labor practices such as a sudden lay-off or nonpayment of wages. Central Labour Relations Commission intervenes in such labor disputes to regulate the situation and provide a relief for union members suffering from unfair labor practices.

The Central Labour Relations Commission, which was established under the Trade Union Law, provides arbitration and mediation in labor disputes based on various labor-related laws, and can conduct investigation and hearings through allegations or official authority in the case of unfair labor practices. However, certain qualifications are required for union members to receive relief, and therefore, the Central Labour Relations Commission is also in charge of assessing whether or not a candidate possesses the necessary qualifications.
