People that want to slack, will do it anywhere, irregardless if in the office or at home.
At my old company we were all office based. I had a colleague who vanished from their computer for hours at a time and there was one colleague who repeatedly managed his other business, being a landlord, loudly over the phone while at work. He also had a phase where he would extend his lunch break playing badminton (without the consent of managers).
Were these colleagues ever disciplined? No.
This company doesn't allow wfh.
For the last 2.5 years I have worked for a different company where I'm completely home based. I always achieve my targets, so my managers are very happy with me.
Point is: Lazy people will be lazy anywhere.
I don't use wfh to look after my children, we pay for a nursery.
I'm also glued to my computer when I'm not on my lunch breaks or morning or afternoon break.
Sometimes I get up and go to the kitchen to make myself a coffee or go to the toilet. But that would happen in an office as well.
My post kind of derails the thread, but I'm responding to people who said everyone wfh is less productive.
It's not true, it clearly depends on the type of employee/person you are.
