Occupational and public health and safety in a changing work environment: An integrated approach for risk assessment and prevention

During recent years the work environment has undergone significant changes regarding working time, years of employment, work organization, type of employment contracts and working conditions. In this paper, consequences of these changes on occupational and public health and safety are examined. These include the disruption of human biological rhythms, the increase of workers fatigue due to changes in patterns of working hours and years of employment, job insecurity and occupational stress, which have a serious impact on workers’ health and may result in an increase in occupational accidents. Unsafe work practices related to workload and time pressure, the impact of work changes on public safety and the deterioration of workers’ living conditions with respect to income, social-family life, health and insurance benefits, are also described. In this context, difficulties that occur due to the changing work environment in conducting effective occupational risk assessments and implementing OSH measures are discussed (for example, frequent changes between tasks and workplaces, underreporting of occupational accidents and diseases, lack of methodological tools, etc.). A fundamental criterion used while studying consequences on health and safety and the relative preventive measures is that health and safety must be approached as ‘the promotion and maintenance at the highest degree of the physical, mental and social well-being of workers’ and not only as retention of their work ability. Limits in combining “flexibility” at work and overall protection of occupational and public safety and health in a competitive market are put forward for discussion.
