A manager explained that he denied a promotion to a worker due to the results of his personal test. His personal test consisted of examining a worker’s car in the parking lot to determine if it was clean and well kept. A car in disrepair and with material strewn around the interior indicated the worker was disorganized and could not be counted on to take care of details. Should the manager’s personal test be used to make promotion assessments? Why or why not? What alternatives to the personal test would you suggest?
