The effects of job demand on work productivity and perceived discomfort level while performing manual handling task

Abstract

This paper aims to investigate the effects of job demand on work productivity and perceived discomfort level at different intensity levels of job demand. Twenty subjects involved in this study comprised of 10 males, and 10 females. All subjects performed an experimental at two different intensity levels of job demand. The data of work productivity and perceived discomfort level were recorded during the task. The results showed that the higher the intensity level of job demand, the higher the work productivity and perceived discomfort level. It can be concluded that working at higher job demand results in higher worker productivity, but proper planning on task design should be implemented to avoid the unwanted risk that will lead to the risk of WMSDs.
