In our monthly surveys of 5,000 American workers and 500 U.S. employers, a huge shift to hybrid work is abundantly clear for office and knowledge workers. ①An emerging norm is three days a week in the office and two at home, cutting days on site by 30% or more. You might think this cutback would bring a huge drop in the demand for office space. ②But our survey data suggests cuts in office space of 1% to 2% on average, implying big reductions in density not space. We can understand why. High density at the office is uncomfortable and many workers dislike crowds around their desks. ③Most employees want to work from home on Mondays and Fridays. Discomfort with density extends to lobbies, kitchens, and especially elevators. ④The only sure-fire way to reduce density is to cut days on site without cutting square footage as much. Discomfort with density is here to stay according to our survey evidence.
