In addition, it identified certain factors which contribute to job stress among Unilever Nigeria Plc. The systematic sampling technique was used to select 150 participants for the study.

In today’s world, stress has become a worldwide phenomenon, which occurs in various forms in every workplace. In today’s work life, employees are generally working for longer hours, as the rising levels of responsibilities require them to exert themselves even more strenuously to meet rising expectations about work performance. Omolara (2008) described occupational stress as the adverse psychological and physical reactions that occur in an individual as a result of their being unable to cope with the demands being made on them.

According to Topper (2007) Vermut and Stensma (2005), Ornels and Kleiner (2003) Verca (1999) in addition, job stressed is caused by lack of resources and equipment, work schedules such as working late or overtime and organizational climate are considered as contributors to staff stress.

Stress can therefore be described as the adverse psychological and physical reactions that occur in an individual as a result of his or her inability to cope with the demands being made on him or her (Moorhead and Griffen, 1998).

Michac (1997) specified causes of stress as follows: poor time management, unclear job descriptions, feelings of inadequacy and insecurity, inability to get things done, lack of communication, bad personal relationships, quality and complexity of tasks. In the same breadth, Dean (2002) viewed stress-related illnesses as the leading cause for low productivity levels in the workplace. Therefore, this is to find out the effect of job stress on staff performance and management and staff to manage stress effectively at Nestle Nigeria Plc. To acquire a clearer understanding of variable of industrial stress.



The current turbulent environment in which some worker conduct their work require that organization examine their practices working in the Unilever Nigeria Plc is an inherently stressful profession with long working hours, heavy workloads, difficult customer and conflicting demand.

This study was necessarily limited in scope due to series of resource limitations as well as practical research limitations and notable ones were: Time constraint, in the sense that time allocated for conducting this study was very short to allow for adequate data collection and this short time had to be divided between the main academic work which included preparation for face to face and examinations.

  • The reluctance of respondents to answer the questionnaire during the data collection process which was critical in providing the needed inputs for the research work. This has been the problem in Nestle, where information flow could be tainted with excessive bureaucracy and suspicion and sometimes fears of victimization by superior officers. Some respondents did not cooperate with the researcher during the data collection period.
  • Financial constraint was also a problem the researcher faced in undertaking the study. This is because the case study area was in Western Region while the researcher was in Eastern Region.
