How training and promotion opportunities, career expectations, and two dimensions of organizational justice explain discretionary work effort
研究基于社会交换和期望理论，发现培训晋升机会通过提升职业期望和员工义务感，促进自由裁量工作努力，且程序公平和互动公平分别调节这一过程。
Contemporary work is highly interdependent, requiring discretionary work effort (DWE) in response to colleagues and customers. According to social exchange theory, organizational support encourages DWE as a form of employee reciprocation. Our model integrating social exchange and expectancy theory anticipates future career returns from organizational support in the form of training and promotion opportunity. Positive career expectations strengthen feelings of employee obligation that are realized in higher levels of DWE. In addition, career expectations are heightened when these opportunities are provided under procedurally just conditions. Furthermore, the relationship between career expectation and felt obligation is strengthened when interactional justice is high. Using structural equation modeling, these hypotheses are successfully tested on a survey of 201 bank employees and their supervisors. Implications for research and practice are discussed.
