I hear you, I work remote for a large utility in another state and can say that not everyone works as hard as some. However I personally work longer hours at home than I did in the office. I dont have to commute each way, and during lunch I can mow my yard, run, or generally do something productive. On mondays I will fish for a few hours in the morning for spring chinook as I am on calls listening and providing updates but not presenting. What a better way to attend a meeting than in a boat (or duck hunting during October (full disclosure my boss knows that I do this, I dont hide it and is good with it).
My division manager is having select individuals start working hybrid due to their perceived work ethic.
My opinion; working from home is great, however its only great if you are working to a level that is acceptable to your customers (internal, external, etc) and have management that is not afraid to call people out.
