This study adopted a dynamic perspective in investigating the effects of employees' perception of equity (PoE) and perception of organizational politics (POP) on their trust in organizations and the subsequent effect of such on their commitment. Data were collected from 216 employees from various industries. The positive effect of PoE and negative effect of POP on employees' trust were confirmed in this study. It is also found that employees' trust in organizations has a positive effect on their organizational commitment. This study also confirmed the mediation of employees' trust on the relationships between POP, PoE, and organizational commitment. Besides, the moderation of employees' trust on the relationships between POP, PoE, and organizational commitment was not confirmed. Implications and suggestions for future research are discussed.
