This has plunged it into jurisprudential obstacles and institutional difficulties. In terms of the main entities, efficacy, dispute settlement mechanisms, etc. collective contracts have their own institutional characteristics. They should be incorporated into the legislative framework for collective labor relations in future legislation, and should link up with trade unions, collective consultation and collective dispute settlement to form a complete system of collective labor law.展开更多

文摘The Labor Contract Law classifies collective contracts as special labor contracts, ignoring the fundamental differences between collective contracts and labor contracts. This has plunged it into jurisprudential obstacles and institutional difficulties. In terms of the main entities, efficacy, dispute settlement mechanisms, etc. collective contracts have their own institutional characteristics. They should be incorporated into the legislative framework for collective labor relations in future legislation, and should link up with trade unions, collective consultation and collective dispute settlement to form a complete system of collective labor law.
