Title The effect of different work-rest schedules on fatigue and performance of a simulated directory assistance operator's task
Bibliographic information Oct. 1994, Vol.37, No.10, Special Issue, p.1697-1707. Illus. 16 ref.
Abstract The directory assistance operator's task with a visual display terminal was simulated to determine the preferable work-rest schedule from among three different schedules: 30min of work followed by a 5min break (30-5); 60min of work followed by a 10min break (60-10); and 120min of work without any break (120-0). The total working duration was 2h. Errors made during the work and subjective responses before and after the working period (2h) were recorded and analyzed. Results showed that the first two work-rest schedules were preferable to the third as significantly fewer errors were made (p ≥ 0.01) when a short break was provided. There was no significant difference (p ≥ 0.10) in errors between the (30-5) and (60-10) schemes. Fewer before and after subjective responses differed significantly for the (30-5) and (60-10) schemes than for the (120-0) scheme. The overall effect of the schemes on subjective responses, however, was not statistically significant at the 5% level. Since both the (30-5) and (60-10) schemes were found acceptable, the (60-10) scheme is recommended since it is easy to implement, causes fewer breaks and therefore fewer work interruptions, and leads to fewer total minutes of break.
