The impact of Shift Work Implementation on sleeping quality and job performance: A case study of semi-conductor manufacturing company

This research is mainly focused on the worker performance of the semi-conductor industry in Taiwan. All we are concerned is how the sleeping quality of the workers on different shifts affects the Job performance. Investigations on workers are undertaken from Silicon Integrated Systems Co-operation, SiS. Pittsburgh Sleep Quality Index, PSQI, and Attitude Towards Shiftwork Scale, ATSS, are used to evaluate workers' sleeping quality and job performance respectively. A questionnaire is designed for collecting relative data. Four hundred well-answered questionnaires are successfully collected. The statistic software package, SPSS11.5, is used to perform t-test, single factor ANOVA analysis and multiple regressions. The evaluation of the correlation between Shift Work Implementation and sleep quality revealed that different work shifts have made significant influences on sleeping quality and job performance. This research also revealed that it would be a good way to reduce accidents resulting from job and to enhance job performance if the employer pays more attention on worker's sleeping quality. For those so called `highly risking group', the company should strengthen worker's health knowledge by implementing necessary courses or practices.
