Abstract：During Kuomintang's southern regime, the labor union's regulation was issued to mobilize labors for revolution and abolish Beijing Government's harsh restriction with labor's rights.Shortly after its founding, the National Government laid down and implemented The Labor Union Law to ensure the harmonious relationship between labors and capitalists, which not only affirmed labors' right of organizing the labor union, contracting and going on strike, but also displayed the tendency of controlling the labor's union and labors' movement.The Labor Union Law was carried out in some aspects, but Kuomintang's strength in labor union was very small.
