Very good point.
I personally know a neighbor who is drawing a full time salary for “working at home” and is only actually putting in about 20 hrs work per week and goofing off the balance of the time.
But apparently fulfilling the obligations such that he’s not getting fired.
I’m deliverables based. I can work 1 hour or 50 hours depending on my workload. As long as people are meeting the expectations set for them, and can make all required meetings, I don’t have an issue with time. This is specific for salaried employees.
Anyone “working” in an office for 8 hours a day is hardly ever productive for 4 hours.
