Fatigue affects labour productivity by impairing the ability of a worker to carry out his/her required duties as expected and in a safe manner. With increase in fatigue comes a reduction in muscular strength, attention to details and loss of concentration. A worker or employee who is gradually losing strength, losing concentration and not giving attention to details is usually more prone to mistakes and would not be able to work at his/her optimum level. Fatigue has also been known to affect employee health. A common example is Chronic fatigue syndrome (CFS), which is a debilitating chronic illness affecting various people worldwide (Lin et. Al., 2011). Those affected endure chronic, incapacitating physical and mental fatigue that is not relieved by rest. This illness is exacerbated by physical or mental exertion and is accompanied by impaired memory and concentration, unrefreshing sleep, muscle and joint pain, and other defining symptoms (www.ncbi.nlm.nih.gov). It doesn’t require rocket science to assert that an employee/worker whose health is adversely affected would never perform any given task to satisfaction.
2) Major factors that contribute to increase in fatigue in workers. * Working conditions
* Noise: Wokocha and Sopruchi (2010) in their study explained that noise effects are both health and behavioural in nature. He further said that unwanted sound can damage Physiological and psychological health. And any worker whose health is affected cannot perform any given task properly. Noise pollution can cause annoyance and aggression, hypertension, high stress levels, tinnitus, hearing loss, sleep disturbances, fatigue, make conversation difficult as well as leads to productivity losses due to poor concentration.
* Heat stress: heat stress occurs when the body takes in and/or produces more heat than it gives off, thus raising the core body temperature beyond normal. It could happen due to...
