Earlier quoted context omitted.
I work in oil and gas, by no means the epicenter of innovation and many of these companies are talking about a moving to a mostly remote work force to save on real estate expenses.
I don't buy the "cost savings" narrative. By a long shot, the largest expense for large companies in employee salaries - rent, by comparison, is a drop in the bucket. What follows is that companies should be most concerned about employee and team productivity rather then office expenses.
Can companies measure productivity of knowledge workers to that granularity?
Office expenses make a relatively small fraction of employee overall expenses. Say 10% to be extremely generous. NYC five-borough average back in 2015 was around $15K per year [1]. A fully-burdened employee expense is around 2X base salary, so a $100K salary position clocks in around $200K fully-burdened, or around 7.5% of that 2015 NYC average figure. I don't currently see companies wholesale changing employment strategies for 10% differentials.
I'm not sure companies can measure productivity down to that expense detail level for knowledge workers.
