INTRODUCTION
1.1 Background of the study
In today’s technological and moving business world, significant and growing percentage of the population work in formal organizations (Heller and Hindle, 1988). People work under a broad array of conditions. While many of these people work indoors, others work outside. Some of these jobs require exposure to intense heat, cold and/ or noise. Hence, while some of these jobs involve high risk injury or illness, others carry low risks. The average working time in the civil service, public and/or private sector encompasses a major part of the individuals life span and occupies a period when physical and mental capacities are fully utilized. Organizations are constantly evolving and the nature of the services provided necessitates differential work schedules.
Here in Nigeria, not all the employees in different organizations do perform the usual 8am to 4pm – five days – a week. Police officers, military personnel, fire fighters, prison warder, nurses, telephone operators among others, do provide 24-hours – a – day service. Muchinsky (1997), posits that in industrial manufacturing companies, some technologies/machine require constant monitoring and operation. Hence, it becomes rational and practical to run these machines continually by having different shift work systems round the clock. He notes further that there are no uniform shift hours, as various companies adopt different shifts.
Usually for nurses, a 24-hour-a-day is broken into three 8- hour- work shifts as follows:
- 7am to 2pm (day shift):
- 2pm to 10pm (swing or afternoon shift)‟ and
- 10pm to 7am (night shift).
Muchinsky finally observes that some companies have employees run only one shift, more so, as workers generally do not like the afternoon and night shift. Consequently, many firms and organizations do rotate the shift on weekly basis so as to carry all the workers along.
Psychologists in industrial settings (Muchinsky, 1988), did and still do investigate the degree to which workers‟ job satisfactions are affected by the shift work, and their abilities to cope with these changes in work schedules.
Since it is the functions of the Nigeria Police Force to maintain internal security here in Nigeria, enforce the laws and orders of the law abiding citizens, arrest, investigate and charge/or prosecute all the offenders in law courts; the police had since adopted three shift work schedules covering from Sunday to Saturday of every week. In order to cover all these duties and police the country effectively, Udonsy 91976), outlines the shift work schedules in this organization as follows:
(a) Morning shift, from 0600 hrs to 1400 hours;
(b) Afternoon shift, 1400 to 2200 hours; and
(c) Night shift. 2200 hours to 0600 hours.
It should be noted at this juncture that the first workers to be initiated to this routine were not policemen, or even firemen, but bakers. Industrialization and global warfare brought shift work into the mainstream (Aveni, 1999). In other words, estimates are that more than 25% of all workers in the U.S. and Europe are now shift workers.
This proposal tends to investigate whether the police personnel actually do have job satisfactions on their job; and/or experience stress in their day to day hassles while working these shifts. Aschoff (1978), in his work posits that shift workers experience many problems ranging from physiological to social adjustments; stressing that most physiological problems are associated with interruptions of the circadian rhythm or internal biological clock; that is to say, our bodies are “programmed” for a certain time cycle. Hence, shift works have been observed to interrupt the cycles of eating, sleeping and working hours; and workers on these shift therefore, tend to experience physiological problems.
In actual fact, the police personnel on these shift works are mostly those on the lower ranks in this force. These are the Inspectors of police, and the Rank and files (made up of Sergeants, corporals and constables); who constitute the life wire of this force. These rank brackets are those mostly running the shift work systems; and are equally seen on the field from time to time. These are the same group of police officers seen by the general public either in their course of being arrested, investigated, and/or probably, while being charged to or prosecuted in law courts. In the course of their enforcing all these laws of the Federation, states and local councils, these officers tend to engage the riotous and unlawfully assembled members of public in physical combat. Not only these, the officers equally do engage the armed robbers in gun battles during their tour of duties. This study therefore, tends to investigate whether these police officers while enforcing all these laws and more, will actually experience stress. Although, researchers have come to agree that stress is found in every organization, industries and in every day‟s live of all human existence; many factors have been advanced by theorists to affect individual‟s job satisfaction. Paramount amongst them is occupational stress. Organizational changes coupled with economic melt down and depression have produced its casualties at both organizational and individual level resulting in stress and conflict. According to cooper (2005), high incidence of stress throughout organizations irrespective of job satisfaction and involvement stress is individually analyzed and every employee has a range of satisfaction which they can feel steady and safe. For MCkenna (1999), stress entails any situation that is seen as burdensome, threatening ambiguous or boring and is likely to affect free flow of performance and satisfaction. A satisfied employee who is committed and involved in his or her job should not encounter stressful circumstances, but Mullins (1999) argued that one potential source of work stress arises from role incongruence and positional role conflict that are not compatible with individual training and experience. Mbieli (2007), noted that occupational stress could act to activate people into action with possible positive behavioural consequences, stressing that the physiological impact upon the person could come in inform of headache, Muscular tensions, fatigue and hypertension. As a complex psychological concept, occupational stress is intrinsically tied into an individual employee‟s perceptual system and as such is seen as subjective phenomenon which influence job satisfaction (Mullins, 1999).
