Thats cool for you, but I'm speaking from my experience about my team's productivity falling off a cliff. Employees that do work when in the office, but wont even respond to email for days when working from home.
That may me a problem of the pepple tou hired, and how you lead them, instead of being a problem of where they work.
Perhaps they were slacking in the office as well, and only giving you the impression that they were busy. You might only be annoyed now because the mask is off.
That's great for you. I have had good experiences long ago in other companies.
In my current company, team leads have little input on employee performance, and nobody has been fired or PIPed in my 100 person department in the last 10 years.
The primary thing that incentivized worker performance was social pressure and visibility from an in person environment.
You might say this is a management problem, and yes, I would agree. However, it still stands that this management problem is greatly exacerbated by hybrid and remote work.
