Much of the history of management and motivation theory is rooted in the desire to understand the factors that contribute to having a satisfied workforce.

The job characteristics model (JCM) holds that if jobs are enriched with high levels of specific job characteristics (i.e., task significance, task variety, task identity, autonomy and feedback), employees will report higher levels of job satisfaction.

This study also evaluated possible moderating influences of growth need strength (GNS; the need for personal growth and development within the job environment) and emotional reactivity (a measure of frustration with perceived obstacles in the work environment). It was hypothesized that employees with higher levels of GNS would respond more positively (via higher job satisfaction ratings) to enriched jobs than would employees with lower levels of GNS. Alternatively, it was hypothesized that employees with lower levels of emotional reactivity would respond more positively (via higher job satisfaction ratings) to enriched jobs than would employees with higher levels of emotional …
