1.1 Introduction
Occupational health education refers to the systematic process of providing workers with knowledge, skills, and attitudes that enable them to recognize workplace hazards, prevent occupational diseases, promote healthy work practices, and maintain their physical and mental well-being throughout their employment (World Health Organization [WHO], 2023). Work-related illness has become one of the major concerns affecting employees and employers across the world. The International Labour Organization (2022) reported that millions of workers are affected annually by occupational diseases resulting from prolonged exposure to hazardous working conditions. These illnesses include respiratory disorders, musculoskeletal disorders, hearing impairment, skin diseases, stress-related conditions, and other health complications associated with workplace activities. The consequences extend beyond the affected workers to organizations through increased absenteeism, reduced productivity, higher compensation costs, and loss of skilled manpower.
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the aim and objectives of the study. Others are significance of the study, scope of work, research hypothesis and questions, limitation of the study and definition of terms.
1.2 Background of Study
Occupational health education has become an essential aspect of workplace management because it promotes the health, safety, and well-being of employees while improving organizational productivity. According to the World Health Organization (2023), occupational health education refers to organized educational activities designed to equip workers with the knowledge, attitudes, and practical skills needed to recognize workplace hazards, prevent occupational diseases, and adopt safe work practices. Effective occupational health education enables employees to understand the consequences of unsafe behaviours and encourages compliance with established health and safety regulations. As industries continue to expand and adopt modern technologies, the need for continuous health education has become increasingly important in reducing occupational risks and creating healthier work environments.
Work-related illness remains a global public health concern because millions of workers continue to experience health problems associated with occupational exposure. According to the International Labour Organization (2022), millions of occupational diseases occur every year, resulting in significant economic losses through reduced productivity, medical expenses, absenteeism, disability, and premature deaths. The organization reported that occupational illnesses often develop gradually following repeated exposure to hazardous substances, excessive noise, dust, vibration, poor ergonomic practices, psychological stress, and other workplace hazards.
Similarly, Goetsch (2020) reported that occupational health education serves as one of the most effective preventive measures against workplace illnesses because informed employees are more likely to identify hazards, follow safety procedures, and adopt healthy workplace behaviours. The author asserted that continuous education creates awareness of occupational risks and encourages workers to participate actively in maintaining safe working conditions. Knowledge gained through structured health education programmes also strengthens employees' confidence in responding appropriately to workplace emergencies and health-related challenges.
In the same vein, Dessler (2020) stated that organizations that invest in employee health education often experience lower rates of occupational illnesses and higher levels of employee commitment. According to the author, occupational health education extends beyond compliance with safety regulations because it promotes behavioural change that encourages workers to value their personal health and collective workplace safety. Continuous learning also enhances communication between management and employees regarding emerging workplace hazards and preventive strategies.
Furthermore, Armstrong (2022) asserted that modern organizations increasingly recognize occupational health education as a strategic human resource management function. The author contended that employee health directly influences productivity, job satisfaction, motivation, and organizational performance. Where employees possess adequate knowledge of workplace hazards and preventive measures, the occurrence of occupational illnesses is significantly minimized.
Moreover, according to Hughes, Hughes, and Ferrett (2021), occupational hazards are unavoidable in many industries, particularly in sectors involving construction, manufacturing, mining, transportation, and energy production. The authors reported that construction workers are frequently exposed to hazardous equipment, manual material handling, repetitive movements, chemical substances, excessive noise, airborne particles, and environmental conditions that may result in chronic occupational diseases if preventive measures are neglected.
Supporting this position, Alli (2008) affirmed that occupational health education encourages employees to develop positive safety attitudes while strengthening organizational safety culture. According to the author, workers who receive regular health education demonstrate greater compliance with workplace safety procedures than those with limited training opportunities. Continuous educational programmes also improve workers' understanding of occupational legislation, health surveillance, emergency preparedness, and disease prevention strategies.
Relatedly, the rapid growth of industrialization has introduced new occupational health challenges across developing economies. According to Rantanen et al. (2017), technological advancement has increased workplace complexity, creating additional health risks associated with automation, hazardous materials, and changing work patterns. The researchers reported that organizations must continuously update occupational health education programmes to reflect evolving workplace hazards and ensure employees remain informed about modern preventive measures. This study is set against the backdrop of examining the role of occupational health education in reducing work-related illness among employees of Julius Berger Nigeria Plc.
1.3 Statement of Problems
Investigation revealed that work-related illnesses remain a significant occupational challenge across many industries, particularly in the construction sector where employees are regularly exposed to physical, chemical, biological, ergonomic, and psychosocial hazards. Although occupational health and safety regulations and workplace policies exist, cases of respiratory diseases, musculoskeletal disorders, hearing impairment, heat stress, fatigue, and other occupational illnesses continue to affect workers, resulting in reduced productivity, increased medical costs, absenteeism, and lower organizational performance (International Labour Organization [ILO], 2022).
Furthermore, many organizations still experience challenges relating to the consistency, quality, and effectiveness of health education programmes, workers' awareness, and adherence to occupational health guidelines. These shortcomings reduce the effectiveness of workplace illness prevention initiatives and increase employees' vulnerability to occupational diseases (World Health Organization, 2023). It is against this backdrop that this study seeks to examine the role of occupational health education in reducing work-related illness among employees of Julius Berger Nigeria Plc.
