A job-scheduling innovation that has helped managers overcome motivation and absenteeism problems associated with a fixed 8-hour workday is a concept called flextime. This flexible working hours program permits employees to design their own 40-hour work week to meet their personal needs (New York Times, Mar. 31,1996). The management of a large manufacturing firm may adopt a flextime program depending on the success or failure of a pilot program. Ten employees were randomly selected and given a questionnaire designed to measure their attitude toward their job. Each was then permitted to design and follow a flextime workday. After six months, attitudes toward their jobs were again measured. The resulting attitude scores are displayed in the table above. The higher the score, the more favorable the employee's attitude toward his or her work. Use a nonparametric test procedure to evaluate the success of the pilot flextime program. Test using a = .05.
