Hm. In a recent business magazine, I read of a study of Walmart's impact on health (University of North Carolina - Greensboro). This one found less obesity (albeit slight) in areas where Walmart offered a full range of groceries. The general conclusion, was that when prices of healthy food were more affordable, people made healthier choices in diet... regardless of education or socio-economics.
I'm sure the Whitehall study (will read it fully later) provides respectable data for what has been commonly known for some time - that when workers have very little control over the "how" of their jobs and little input into improving work-life and the overall success or efficiency of the enterprise - stress levels are much higher. It's generally accepted nowadays, is it not, that this kind of stress creates psychosomatic health problems.
I take all this scientific validation of what people have been experiencing, as a sign of hope that business will change some of it's current practices. Well-being of workers, a sense that they're valued as people and not just for productivity statistics... do directly and indirectly impact the success of businesses.
