Perhaps we should put these people all together in one area so one manager can get them off the dime. Like a big building where they all have to sit in the same room so it is easy to see who is working and who is just occasionally nudging their desk while they watch porn.
We could call this place, an office.
People can look busy in an office.
If management is unable to measure productivity properly that means nothing.
If management can measure productivity properly then there is no need for the office.
Remote work—in good organizations—forces management to fully understand the work that is needed—and measure it.
