Although the model was somewhat more complex than many think today, its two primary determinants of turnover were perceived desirability of movement and perceived ease of movement. Although this model was never extensively tested, the key constructs have been included in many subsequent models. There were several advancements in turnover theory during the 1970s.
Unmet expectations lead to dissatisfaction which lead to turnover.
There is some evidence to support this contention although the effect is small. Basically this model, posits that beliefs about an action are related to attitudes toward the action which lead to intentions to act, and finally the action in this case, turnover. However, subjective and social norms have a moderating influence on the intentions to quit. This significant advance in the turnover literature helped to explicate the underlying processes related to turnover. Mobley and colleagues proposed an expanded version of this model in 1979 which includes more constructs.
