Four assumptions of the expectancy model

The expectancy model states that people are motivated to work when they believe that they can achieve things they want from their jobs. 

 

A basic premise of the expectancy model is that employees are rational people. 

 

Four assumptions about the causes of behavior in organizations provide the basis for this model. 

 

First, a combination of forces in the individual and environment determines behavior. 

Second, individuals decide their own behaviors in organizations, even though constraints may be placed on individual behavior. 

Third, different individuals have different needs and goals.
  
Fourth, individuals decide among alternatives based on their perceptions of whether a specific behavior will lead to a desired outcome.
