In the 1950’s and 60’s, employee health was seldom factored into office design. Clerical staff in the central typing pool worked under flickering fluorescent lights and did not enjoy either privacy or access to windows and views. In the coveted corner office, a long day was likely to be fueled by coffee, cigarettes and the infamous 3-martini lunch—and there was no company gym, volleyball court or cocoon-like break room to relieve stress. At the same time, people at work frequently left their desk and walked across the office to deliver a memo, retrieve a file or set up a meeting. Incidental exercise—walking—was routine. And office workers rarely worked more than 10 hours a day. By the end of the 20th century, that was no longer the case.
