They’re bad for concentration, motivation, stress – and they don’t even make it easier for employees to communicate, new research indicates

In case you still needed persuading that open-plan offices were devised by Satan himself in one of the deepest caverns of hell, the Harvard Business Review delves into new research showing just how frustrating people find them – and just how paltry, on the other side of the scale, are the benefits they bring. Using data from surveys of 42,700 American office workers, researchers Jungsoo Kim and Richard de Dear conclude that it’s not other people’s mess that bothers us the most, nor lack of personal space, nor even noise level per se, so much as a “lack of sound privacy” – hearing other people’s conversations, and perhaps equally crucially, knowing that other people can hear yours. 

....

We already know that open-plan offices have been associated with less persistence at challenging taskslower motivationhigher stress and blood pressure, and more. But Kim and Dear’s work, published in the December 2013 issue of the Journal of Environmental Psychology, puts paid to any suggestion that the benefits of easy communication between workers – effortless exchange of information, useful chance conversations sparking new ideas – outweighs these irritations. Employees in private settings actually rated "ease of interaction" as better, overall, than those in open offices. Perhaps that's because it’s so hard to hold a useful conversation with one other person when half your mind’s on the question of who else might be eavesdropping?

Stress and open-office noise.

Abstract: Forty female clerical workers were randomly assigned to a control condition or to 3-hr exposure to low-intensity noise designed to simulate typical open-office noise levels. The simulated open-office noise elevated workers' urinary epinephrine levels, but not their norepinephrine or cortisol levels, and it produced behavioral aftereffects (fewer attempts at unsolvable puzzles) indicative of motivational deficits. Participants were also less likely to make ergonomic, postural adjustments in their computer work station while working under noisy, relative to quiet, conditions. Postural invariance is a risk factor for musculoskeletal disorder. Although participants in the noise condition perceived their work setting as significantly noisier than those working under quiet conditions did, the groups did not differ in perceived stress. Potential health consequences of long-term exposure to low-intensity office noise are discussed.

The impact of the physical environment on the psychological well-being of office workers.

Abstract: This paper examines the relationship between the physical office environment and the psychological well-being of office workers. The results indicate that adverse environmental conditions, especially poor air quality, noise, ergonomic conditions, and lack of privacy, may effect worker satisfaction and mental health. The data also provide substantial evidence that worker assessments of the physical environment are distinct from their assessments of general working conditions, such as work load, decision-making latitude and relationships with other people at work. Stated another way, people who reported problems with the physical environment could not simply be characterized as dissatisfied workers exhibiting a tendency to 'complain' about every aspect of their working conditions. Taken together, these findings lend support to the position that the stress people experience at work may be due to a combination of factors, including the physical conditions under which they labor. Both theoretical and practical considerations arise from these data, including the need for work site based health promotion and stress reduction programs to consider both the physical and psychological design of jobs.
