Abstract:The principle of labor rules and regulations validity mainly consists of principles of clarity, proportionality and exception. In the author's view, the principle of clarity should be discarded, the proportionality principle should be used for reference, and the principle of exception needs to be identified. And the prospect of these relations can be divided into two systems of effectiveness model and benchmark model. The effectiveness model, in turn, can be divided into the general effect model and the special effect model. The general effect model refers to that the law (labor law or benchmark regulation) is the highest potency, the collective contract the second, the labor contract of the labor regulations (including labor discipline) the lowest. The benchmark model refers to that the labor regulation benchmark is the highest, labor contract benchmark the second, collective contract, the law (labor law or benchmark regulation) the lowest fallback provision or the bottom line
