A recent study in the journal Ergonomics used longitudinal data to compare sick leave rates among 1,852 Swedish employees working in different types of offices: open offices of different sizes, private offices, shared private offices, flexible layouts with meeting rooms but no individual workstations, and more. Surprise! Open offices, where there are few barriers between you and your colleague's every whisper, sneeze and cough, result in "significant excess risk" for needing to take sick leave. The effect was particularly prevalent among women, although for men, flex-offices were particularly associated with more short-term sick leave.
Why that may be, the researchers can't yet say, but they do have some hypotheses. It could be related to environmental factors, like the fact that excess noise, lack of privacy, and the inability to control your personal environment stress people out. It could just be that the risk of infection increases when you throw a bunch of people together. Or, the researchers postulate, it could be that group dynamics in different office types influence whether people take days off or not—employees may be less willing to take a sick day if they work in a very small office where their coworkers depend heavily on their participation, versus in a large open office.
Before you revolt and declare your desk a health hazard, there are a few reasons to take these findings with a grain of salt. The study was based on self-reported data from two surveys, in 2010 and 2012, asking people about how often they took sick leave in the past 12 months. Maybe someone forgot about the week she was out with the flu, or remembered one day of food poisoning feeling more like seven. It also didn't control for the baseline health of the participants. So it's hard to point to the open office as the cause of employees taking sick days. The researchers caution that "the results of this explorative study should only be viewed as a first step in the investigation of the long-term effect of the office environment's impact on employee sickness absence."
But it's not hard to imagine that all those serendipitous collegial encounters might spread germs as well as ideas.
