Shift work research findings are grounds for big concern

A scientific symposium held in Canada in April 2010 has raised some serious concerns about the health impacts of shift work.  Some of the evidence has existed for a while but collecting it all together makes one wonder how companies can justify shift work in the face of such high risks to workers’ health.

From the evidence presented at the symposium, workers will be tired at work when working shift work and are more likely to be injured than those on day shift.  Some workers have an increased risk of breast cancer.  Foetal growth in some pregnant women may be impeded.  Circadian disruption may encourage the growth of tumours and an international agency is convinced sufficiently of the risks to determine that shift work itself is probably carcinogenic.

The Occupational Cancer Research Centre and the Institute for Work & Health should be applauded for making the evidence presented at the symposium publicly accessible.   Continue reading “Shift work research findings are grounds for big concern”

Canadian research shows occupational link to breast cancer

“Certain occupational exposures appear to increase the risk of developing postmenopausal breast cancer”, is a conclusion reached by Canadian researchers and released in April 2010 edition of the Journal of Occupational & Environmental Medicine.

The researchers acknowledged that “some findings might be due to chance or to undetected bias some findings might be due to chance or to undetected bias”, but there is enough evidence to generate concern in occupational sectors and, often, the media shows increased interest in breast cancer research.

Several Australian scientists have advised caution on interpreting the research findings.   Continue reading “Canadian research shows occupational link to breast cancer”

Promising work flexibility and health research doesn’t go anywhere

“A new evidence review* suggests that giving employees more flexibility over their work schedules is likely to boost their health as judged by measures like blood pressure and stress. But interventions that are motivated or dictated by the needs of the employer, such as cutting hours, either have no effect on employee health or make it worse.

“Control at work is good for health,” said review co-author Clare Bambra, a researcher at Durham University, in England. “Given the absence of ill health effects associated with employee-controlled flexibility and the evidence of some positive improvements in some health outcomes,” Bambra said, more flexibility in work schedules “has the potential to promote healthier workplaces and improve work practices.”

The above quote indicates that new evidence may help all of us in assessing the benefits or otherwise of allowing employees to telework, or of readjusting work practices to improve health and safety at work.

BUT

an article issued in support of the research clearly identifies the risks of drawing almost any firm conclusions from the evidence other than that more research is required: Continue reading “Promising work flexibility and health research doesn’t go anywhere”

European OHS statistics show the way for other regions

On 19 January 2010 EuroFound began the fieldwork necessary for the next in its series of surveys of working conditions in Europe.  According to the media release:

“Eurofound launches the fieldwork for the fifth European Working Conditions Survey, involving face-to-face interviews of workers in 34 European countries. This critical and timely research tracks the current state of working conditions in Europe, highlights the quality of work and employment, and monitors changing trends. The first findings of the survey will be presented at the end of 2010.”

The beginning of fieldwork is far less interesting than the end of the fieldwork but the announcement does remind us of the statistics that the organisation has been able to amass since 1991. Continue reading “European OHS statistics show the way for other regions”

Shoemaking in South East Asia – book review

Some of the best OHS writing comes from the personal.  In a couple of days time a new book will go on sale that illustrates big issues from a niche context and brings to the research a degree of truth from the personal experiences of the author.

Pia Markkanen has written “Shoes, glues and homework – dangerous world in the global footwear industry” which packs in a range of issues into one book.  The best summary of the book comes from the Preface written by the series editors.

“Pia Markkanen’s extraordinary first hand investigation of the dangers of home work in the shoe industry in the Philippines and Indonesia is an important contribution to our understanding of work, health and the global economy. She also carefully documents the intersection of gender relations and hierarchy with the social relations of “globalised” economic development and reveal as the important implications for the health of women, men and children as toxic work enters the home.”

As one reads this book, local equivalents keep popping into the reader’s head.  For instance, Markkanen’s discussion of the home as workplace raises the definition of a “workplace” that is currently being worked through in Australia.  She briefly discusses the definition in her chapter “Informal Sector, Informal Economy” where she refers to an ILO Home Work Convention, and usefully distinguishes between the homeworker and the self-employed, a distinction that Australian OHS professionals and regulators should note.

Markkanen does not impose a Western perspective on her observations and acknowledges that regardless of the global economic issues and social paradigms, “shoemakers felt pride for their work”.  This pride goes some way to explaining why workers will tolerate hazards that others in other countries would not.  In many OHS books this element is often overlooked by OHS professionals and writers who are puzzled about workers tolerating exposure and who look to economic reasons predominantly.

In South East Asia, limited knowledge can be gleaned from literature reviews as the research data is sparse.  Markkanen interviewed participants first hand and, as mentioned earlier, this provides truth and reality.  She describes the shoe makers’ workshops in Indonesia:

“Shoe workshops are filled with hazardous exposures to glues, primers, and cleaning agents, unguarded tools, and dust.  Work positions are often awkward, cuts and burns are common, as are respiratory disorders.  Asthma and breathing difficulties are widespread when primers were in use.  Workers were reluctant to visit doctors because of the expense.”

She then reports on the interviews with Mr. Salet, a shoe manufacturer, Ms. Dessy, the business manager, Mr Iman, the business owner, Mr Ari, a skilled shoemaker, and many others.

Markkanen also illustrates the shame that the minority world and chemical manufacturers should feel about the outsourcing of lethal hazards to our fellows.  In the chapter, “Shoemaking and its hazards”, she writes:

“Shoe manufacturing will remain a hazardous occupation as long as organic solvents are applied in the production.  It is notable that in 1912, the Massachusetts Health Inspection report declared that naphtha cement, then in use for footwear manufacturing, was considered hazardous work.  The 1912 report also referred to a law which required the exclusion of minors from occupations hazardous to health – the naphtha cement use was considered such hazardous work unless a mechanical means of ventilation was provided and the cement containers were covered…. minors were prohibited from using the cement.  Almost a century later, hazardous footwear chemicals are still applied – even by children – in the global footwear industry.”

There is little attention given to the OHS requirements of majority world governments by OHS professionals in the West, partly because the outsourcing of manufacturing to those regions has led to the reporting of OHS infringements and human rights issues more than information about the legislative structures.

Markkanen provides a great section where she describes the OHS inspectorate resources of the Indonesian Government and the fact that Indonesian OHS law requires an occupational safety and health management system.  Granted this requirement is only for high-risk industries or business with more than 100 employees but there are many other countries that have nothing like this.  Markkanen quotes Article 87 of the Manpower Act 2003:

“Every enterprise is under an obligation to apply an occupational safety and health management system that shall be integrated into the enterprise’s management system.”

It is acknowledged that this section of legislation is hardly followed by business due to attitude and the lack of enforcement resources but we should note that safety management is not ignored by majority world governments.

Lastly, Markkanen provides a chapter on the gender issues associated with the shoemaking industry.  She makes a strong case for the further research into the area but it is a shame that to achieve improvements in women’s health the reality is  that

“women’s health needs female organizers and female women trade union leaders who understand women’s concerns”.

Some male OHS professionals may be trying to be “enlightened” but this seems to not be enough to work successfully in some Asian cultures.

Overall this book provides insight by looking at a small business activity that illustrates big issues.  The book is a slim volume of around 100 pages and it never becomes a difficult read because it is concise and has a personal presence that other “academic” books eschew.  As with many Baywood Books, the bibliographies are important sources of further reading.

At times it was necessary to put the book aside to digest the significance of some of the information.  Occasionally the reality depicted was confronting.  Baywood Books could do well by encouraging more writers to contribute to it Work, Health & Environment Series.

The meaning of work

A weekly radio program broadcast on Australian community radio station 3CR, Stick Together, broadcast a lecture by Barbara Pocock on the meaning of work.

Barbara Pocock is a leading workplace researcher and remains the voice on work/life balance.  She is always worth reading and listening to.  It is impossible to management workplace safety without continuing to learn what work is and how people look at work.  A podcast of the Stick Together program is available for download.

Pocock says that many of the perspectives on work are negative and is therefore approached as a chore.  She talks about how laborious jobs have declined in relation to technology and client demand and discusses

  • “efficacy, identity, contribution, vocation
  • social connection
  • opportunity to learn
  • positive spillover from work”

Global OHS statistics and trends

It is very easy to forget that workplace health and safety is a global issue.  The pressures of work and the daily OHS issues can constrict our perspective for so long that we are surprised when we are reminded that people work everywhere and are therefore in danger in some way.

An article (citation below) from the  Scandinavian Journal of Work, Environment & Health released online on 12 November 2009 is just one of those reminders that we need every so often.  The article is called “The global and European work environment – numbers, trends, and strategies” and says

“We have estimated that globally there are 2.3 million deaths annually for reasons attributed to work.”

For the statistics junkies, the article goes on to report that 1.95 million of the annual deaths are due to illness and

“The average rate of disability and absence from work can be some 25% of the workforce in Europe.”

“The biggest causes of work-related illness in Europe are musculoskeletal diseases and psychosocial disorders (mental health)….”

“Work-related stress….affect(ed) an estimated 22% of EU workers in 2005…”

By looking at a variety of statistical records, the authors conclude that

“In the present political situation and serious economic downturn, legal measures need to be supplemented with economic justification and convincing arguments to reduce corner-cutting and avoid long-term disabilities, premature retirement, and corporate closures due to a poor work environment.”

The relationship between fatalities and other outcomes of work injuries and illnesses

The researchers advocate an integrated approach to managing safety in a workplace and list a “toolbox” of suggested areas.  Many of these are already in place in many management systems.

This sort of global data is not going to change the management or operational practices in individual workplaces.  That change will mostly come in response to site-specific events or initiatives.  Governments need to know these statistics and trends so that they may plan strategic programs or structure their legislation but it is equally important for citizens and OHS professionals to be aware of this data for it is the citizens who hold governments accountable.
