I used to work at a large corporation who had a ton of middle management. For a few years people had the ability to work from home in an emergency, but it wasn't something normal and you were expected to be in the office otherwise. At this point, people were working from home less than 2% of the time.
Then we got a new manager, who was a huge promoter of "ROWE" or Results Only Work Environment. within 6 months, 90% of the office were working from home 90-95% of the time. I used to come in on Monday's and the office would be empty, dead, not a peep and where six months ago, we had 15-20 developers working, we now had one or two. You seriously could have mistaken the office as being on holiday - it was crazy.
As such, the middle managers suddenly had a lot less to do. Since results were all that mattered, their jobs of micro-managing all the daily/weekly/monthly metrics they were following and tracking and emailing developers pretty much went out the window. Three months later, 5 managers either quit or were laid off because ROWE made their jobs essentially obsolete.
The funny part is the manager who was all about ROWE ran into some roadblocks for his other initiatives and left shortly thereafter (he lasted just over a year). Once he left, upper management quickly revoked ROWE (even though it had been incredibly successful and raised production 11%) and required people to be in the office 5 days a week unless it was for an emergency.
