Job satisfaction is typically defined as an employee’s level of positive affect toward his or her job or job situation... Along with positive affect, we can add both a cognitive and a behavioral component to this definition... The cognitive aspect of job satisfaction represents an employee’s beliefs about his or her job or job situation; that is, an employee may believe that his or her job is interesting, stimulating, dull, or demanding—to name a few options... The behavioral component represents an employee’s behaviors or, more often, behavioral tendencies toward his or her job. An employee’s level of job satisfaction may be revealed by the fact that he or she tries to attend work regularly, works hard, and intends to remain a member of the organization for a long period of time.
