Here's the payload for those not wanting to hunt for it in the paper:
"We find a highly significant 12% increase in performance
from home-working, of which 8% is from working more minutes of their shift period (fewer breaks and sick-days) and 3% from higher performance per minute. We find no negative spillovers onto workers left in the office. Home workers also reported substantially higher work satisfaction and psychological attitude scores, and their job attrition rates fell by over 50%."
Somewhere (can't recall) it was said that those who predominantly worked from home, while effective as a workforce, suffered from lack of visibility and thus tended to not get raises or promotions as much as those who remained in the office (I assume this was normalized for responsibility/position).
IIRC that was mentioned here and was most likely to occur in teams where just a few worked remotely while the majority came into the office and interacted with management. The same thing will happen if you come to work, quietly do your job, quietly leave and don't interact with management.
Management won't promote the person they don't remember.
