The study investigated and evaluated job stress and its effect on employees performance at Unilever Nigeria Plc. The study sought to find out how work related stress could affect the productivity of staff of Unilever Nigeria Plc. In addition, it identified certain factors which contribute to job stress among Unilever Nigeria Plc. The systematic sampling technique was used to select 80 participants for the study. The result of this study revealed that work load was the major cause of job stress on employee performance in Unilever Nigeria Plc. It was further observed that respondent in order to relieve stress often walk around and visit other colleagues in their office to discuss matters irrelevant to work thereby affecting productivity at the Unilever Nigeria Plc.

Health-wise, some members of staff of Unilever Nigeria Plc had developed chronic back pain, an effect of long sitting hours and standing hours at work. Management commitment to staff issues such as paying attention to work load conflicts, supervisors recognition of outstanding output of staff and the introduction of proper stress management training programmes were perceived as significant steps which if embraced were identified as major contributory factors that could contribute to improve productivity of staff and boost output of staff.
















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 Unilever Nigeria Plc. To acquire a clearer understanding of variable of job 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. The effects of stress are evidenced as increase errors in lateness to work, low productivity and increased sick leaves. Despite the extremely negative effect of job stress on human body and work performance.

The following questions guided the study

  • What are the effect of stress on the productivity of the staffs in an organization?
  • How do staffs in an organization handle stress?
  • What stress management strategies have been employed by organization to help staff to manage stress?


Research hypothesis are in two forms:

H0:      There is no significant relationship between job stresses and job productivity.

H1:      There is a significant relationship between job stresses and job productivity.

H0:      Organization do not adopt any stress management strategies to help staff manage stress.

The purpose of the study was to find out the effects of stress on staff productivity. The researcher ensures the effective management of stress for their employees. The study will also add to existing store of knowledge. It will also provide suggestions on how to reduce the effects of stress on output. Again, it will be a source for further research and of relevance to stakeholders.


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 Unilever, 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.
