Abstract: Psychological contract breach occurs when employees perceive that their employers fail to deliver on what they perceive was promised. The present paper distinguished the psychological contract breach and the psychological contract violation conceptually. And we reviewed the empirical researches, at home and abroad, on the effects that psychological contract breach has on employees’ attitudes and behaviors from the aspects of direct effects and indirect effects (the mediating effects and the moderating effects), and commended on the deficiencies of the research methods and theoretical basis. Furthermore, we gave some suggestions to the future researches which are: (1) create psychological contract scale for Chinese enterprises based on the Chinese culture background; (2) inspect the effects that the psychological contract breach has on both sides in a dynamic process from two separate perspectives-the employees’ and the employers’ perspectives.

Key words: psychological contract, psychological contract breach, attitude, behavior
