> Unfortunately for the believers, new research mostly runs counter to this, showing that offices, for all their flaws, remain essential. A good starting point is a working paper that received much attention when it was published in 2020 by Natalia Emanuel and Emma Harrington, then both doctoral students at Harvard University. They found an 8% increase in the number of calls handled per hour by employees of an online retailer that had shifted from offices to homes. Far less noticed was a revised version of their paper, published in May by the Federal Reserve Bank of New York. The boost to efficiency had instead become a 4% decline.
The researchers had not made a mistake. Rather, they received more precise data, including detailed work schedules. Not only did employees answer fewer calls when remote, the quality of their interactions suffered. They put customers on hold for longer. More also phoned back, an indication of unresolved problems.
