It is becoming more and more apparent that shift work has a negative effect on workers’ performance, injury level, sleep quality and quantity and overall health.  In recent blogs I’ve shared studies and articles that showed the increased work-related injuries in shift work employees, and the negative effects caused by worker fatigue in general.  Another study, Job Stress and Work Schedules in Relation to Obesity was recently released in the Journal of Nursing Admi

Snow has been pretty scarce where I live in MN this winter so I haven’t had much opportunity to push and shovel snow.  We finally got some snow this morning—a little over an inch (I’m a snow lover so yes, I’m excited for even an inch or two of snow!).  I went out to clear the driveway with the shovel with my straight handled snow shovel.  One would think that as an ergonomist I must use the “ergonomic” handled ones, right?  Wrong.  I love my straight handled snow shovel.  [I put “ergonomic” in quotes because there are no standards for companies to use the term on their products.  I often fi

In my previous blog I discussed the indisputable fact that working extended hours causes worker fatigue and lowers performance.  This was regardless of the time of day that was worked.  Another aspect to consider is the effect of shift work on worker performance.  I will define shift work as either the night shift or rotation shifts working normal amount of work hours (8-10 hours/shift).  A recent study of Canadian workers shows some interesting results in regards to work injuries.  The study covered a 10 year period, 1996-2006, and examined the injury rates of workers differentiated by the

In an article I wrote last year, “To Stretch or Not To Stretch”, I concluded that stretching programs for the purpose of reducing injuries were not shown to be or not be effective.  As such, businesses should closely evaluate the costs of devoting time and resources to stretching programs compared to the supposed benefits.  I’d like to follow up that article with research done by Hess and Hecker on Workplace Stretching Programs:  The Rest of the Story.  In their research

How many people or friends do you know who work 12+ hour shifts or work long shifts several days in a row with little sleep?  How many professions do you whose work requires the same?  I can name at least 12 friends that I know who long hours.  I also know the toll those hours take on them professionally and personally.  As for professions, probably the first ones that come to mind are doctors, nurses, police, firefighters and military personnel.  There are other workers who have similar work demands, although they may occur when production demands (i.e.

It’s common for people to make New Year’s resolutions that address their fitness and health.  It’s also the time of year that companies develop goals and strategic initiatives for the year ahead as well.  One resolution that companies should consider pertains to Total Worker Health™.  It used to be that companies only had employee health and safety programs.

Are you aware of the National Prevention Council?  Its formation was part of the 2010 Affordable Care Act.  The council is chaired by the US Surgeon General and the other members are the leaders of 17 federal departments, agencies and offices.  The council’s purpose is to promote prevention and wellness.  The council released its National Prevention Strategy in June 2011.  According to Surgeon General Regina Benjamin, MD, the strategy will “move us from a system of sick care to one based on wellness and prevention”.  She goes on to say, “We also know that many of the strongest predictors of

If I had a penny for every time I’ve heard that ergonomics is “expensive” I wouldn’t be writing this blog but instead sitting on a beach somewhere.  The perception that ergonomics is expensive seems to be a widely held belief in many people I’ve talked to whether they are clients, potential clients or at people I’ve met at conferences, meetings or networking events.  I’ve seen this perception prevent the implementation of ergonomic programs at more companies that I’d care to admit.  The question that must be asked is, “Is the perception true or false?”  The answer is both, true and false, d

“Ergonomics doesn’t work.”  “Ergonomic changes didn’t solve the problem—it continues just the same.”  “Ergonomics just frustrates me—it just doesn’t seem to produce the type of changes (benefit) I think it should.”  Those of words I’ve heard from clients who have tried ergonomics and obviously, have not had good results.  I know more people who are frustrated with ergonomics or don’t put much stock into ergonomics after seeing little or no benefit from implementing “ergonomic changes”.  Have you ever heard or said those words?  If so, keep reading.  I’d like to address what I see are the to

In this blog series I’ve been focusing on ergonomic assessments.  The first one dealt with the 5 components of an assessment.  The second dealt with the type of questions to ask for the gathering background information and physical ergonomics.  In this blog I want to provide some examples that relate to understanding and examining the impact of the mind and the organization.
