I've been working from home for 15 years and such articles make me laughing. Media simply try to fill the vacuum they are in and their efforts are simply ridiculous.
I kind of feel you, but those people are new to this (employers and employees). They have no idea what they are doing, they are scared and they want someone to resolve this issue for them. Any experienced person just turns off their phone or snoozes notifications. People have flex working hours and some co-workers send me messages at 1 am. Should they go to jail or what? Everything could be solved with a little bit of education.
You know, I could tell a lot about self-organisation, how to arrange things, and how to make your wife and children think you're absent when they see you working in the dinning room. But you're right, people en masse are new to this.
