A new study led by Arie Shirom at Tel Aviv University reveals the powerful impact of the workplace on longevity. The researchers tracked 820 adults for twenty years, starting with a routine health examination in 1988. The subjects worked in various professions, from finance to manufacturing to health care. They were interviewed repeatedly about conditions at their workplace, from the behavior of the boss to the niceness of their colleagues. Over the ensuing decades, their health was closely monitored, allowing the scientists to control for various medical conditions, such as high blood pressure, smoking and depression.
The first thing the researchers discovered is that office conditions matter. A lot. In particular, the risk of death seemed to be correlated with the perceived niceness of co-workers, as less friendly colleagues were associated with a higher risk of dying. (What’s troubling is that such workplaces seem incredibly common.) While this correlation might not be surprising – friendly people help reduce stress, and stress is deadly – the magnitude of the “friendly colleague effect” is a bit unsettling: people with little or no “peer social support” in the workplace were 2.4 times more likely to die during the study, especially if they began the study between the ages of 38 and 43. In contrast, the niceness of the boss had little impact on mortality.
What’s driving this effect? Why are caustic co-workers so unhealthy? One interesting factor influencing the correlation between peer social support and mortality was the perception of control. This makes sense: the only thing worse than an office full of assholes is an office full of assholes telling us what to do. Furthermore, this model of workplace stress being driven by the absence of control has plenty of empirical support. The most impressive support comes from the Whitehall study, an exhaustive longitudinal survey launched in 1967 that tracked some 28,000 British men and women working in central London. What makes the study so compelling is its uniformity. Every subject is a British civil servant, a cog in the vast governmental bureaucracy. They all have access to the same health care system, don’t have to worry about getting laid off, and spend most of their workdays shuffling papers.
