Employee substance use and on-the-job behaviors

Substance use and job behaviors were assessed in a sample of municipal employees from a large city in the southwestern United States. Job behaviors included psychological and physical withdrawal, positive work behaviors, and antagonistic work behaviors. Employees who reported substance use at or away from work were found to more frequently engage in withdrawal activities and antagonistic work behaviors than did nonusers, although users and nonusers did not differ on positive work behaviors. We tested hierarchical regression models to determine whether substance use contributed unique variance to the prediction of job behaviors after we controlled for variance associated with personal and job background domains. Substance use added unique variance to the prediction of psychological and physical withdrawal behaviors but not to positive or antagonistic work behaviors.
