Psychologists have found that the implementation of policies allowing work schedules to be tailored to individuals' needs does not typically increase managers' job satisfaction or their efficiency -- although this may be because most managers already have the autonomy to adjust their own schedules. But these flexible-schedule policies do increase job satisfaction, productivity, and attendance among nonmanagerial employees. The benefits dissipate somewhat over time, however, and they are reduced even further if schedules are too elastic. Which one of the following statements is most supported by the information above? ["Flexible-schedule policies should be expected to improve the morale of some individual employees but not the overall morale of a company's workforce.", 'Implementing flexible schedules would be an effective means of increasing the job satisfaction and efficiency of managers who do not already have scheduling autonomy.', 'The typical benefits of flexible-schedule policies cannot be reliably inferred from observations of the effects of such policies on managers.', "Flexible schedules should be expected to substantially improve a company's productivity and employee satisfaction in the long run."]
