Shift work is becoming increasingly prevalent in our society, with 17% of the full-time work force and 36% of the part-time work force working non-standard shifts (Beers, 2000). The goal of this study was to explore the relationships between several shift work variables and retention of employees working in a retail organization that is open 24-hours a day. Results indicated no significant differences between workers in fixed versus mixed shift schedules on job satisfaction or role stress. Contrary to my hypothesis, mixed shift workers reported higher levels of commitment and remained with the organization longer than fixed shift workers. As predicted, night shift workers reported lower levels of job satisfaction and organizational commitment than evening workers. However contrary to predictions, there were no significant differences between morning and night shift workers. Supervisor support did not moderate the relationship between shift work and commitment, satisfaction, or role stress. However is [sic] was a significant moderator of the relationship between day versus evening shift and role stress, with individuals working evening shifts and perceiving high levels of supervisor support remaining with the organization the longest.
