Shift work and health
Work has long been acknowledged as an important social determinant of health and health inequalities in industrialised societies. The past two decades have seen the development of labour market practices in which skills, working hours, contracts, conditions, pay and location are more flexible. The emergence of the 24 hour society has raised concerns about the effects of shift work on health and wellbeing Shift work involves working at times and on days that may make it difficult to maintain a balanced domestic and social life “work-life balance”. Shift work may therefore be an important determinant of health and wellbeing for many workers.A range of interventions has sought to address the negative health effects of shiftwork, including reductions in shiftwork (especially night shift), redesign of the shift system according to ergonomic criteria, educational interventions (e.g. to help workers cope with shiftwork), improvements in working conditions (reducing noise or improving unfavourable working environments) and regular medical surveillance and counselling. However, no existing systematic review has evaluated the effects of changes in the organisation of shiftwork on health and well-being. This review aims (i) to summarise existing evidence about the effects and cost-effectiveness of organisational, and other interventions, (ii) to identify issues of differential effects - what works, in which groups of workers; and (iii) to contribute to the development of new interventions.
The past two decades have seen the development of labour market practices in which skills, working hours, contracts, conditions, pay and location are more flexible. The emergence of the 24-hour society has raised concerns about the effects of shift work on health and well-being. Shift work involves working at times and on days that may make it difficult to maintain a balanced domestic and social life, or work-life balance. Shift work may therefore be an important determinant of health and well-being for many workers. One common change to the organisation of shift work involves introducing a Compressed Working Week, in which the hours worked per day are increased whilst the days worked are decreased - in order to work the standard number of weekly hours in less than five days. Such a working pattern is a radical break with the traditional eight-hour working day. Introducing the Compressed Working Week seems to improve the work-life balance of shift workers, with few adverse health or organisational effects. It is also generally beneficial, or at least not detrimental, to health in the short-term. The Compressed Working Week could be an important tool for both policy-makers and employers in terms of promoting healthier work places and improving working practices.Conducted by: C Bambra1, M Petticrew1, M Whitehead1, A Sowden1, J Akers1
