In societies where all of this is encoded in law they seem to be doing worse off than where these things are based on trust.
> Employees have the right to refuse contact outside their working hours unless that refusal is unreasonable. This means an employee can refuse to monitor, read or respond to contact from an employer or a third party.
We don't have "at-will employment", so you can't be fired for arbitrary reasons. And if you were to treat someone poorly or fire them for refusing to be available for free after hours, you would end up in serious trouble in front of the Fair Work Commission.
This is the main value of governments, have them regulate these things for your protection!
I once had a hiking partner on a classic hut to hut hike on the north island (Tongariro Northern Circuit, it's where they filmed mount doom and mordor) who walked out of the hut at night to find a ridge to get service to do a job interview with a company in the UK.
The disconnection from real life is a huge part of why I like to wander off into the woods, and I pray that I will never be expected to have internet in these remote places.
Frankly in Switzerland, we already have connectivity everywhere, and people don't expect that.
Also its up to yourself putting up boundaries.
It's obviously possible to say "I'm going to be unreachable", but people don't really like that, and it becomes a push-pull unless you're doing something where you genuinely have no service or connection. For a long time, being on an airplane allowed this sort of ability to disconnect: even if there were $5/minute in-seat phones, nobody reasonably expected to be able to reach you if you said you'd be on a flight. A few hours where you could fully tune out the noise of the world, no questions asked.
Wilderness backpacking trips have maintained this sort of unreachableness fairly well–I've had a Garmin inReach for years, and used it to keep family apprised of our movements, and once to coordinate a fairly serious situation where a large wildfire kicked up near our exit, but ultimately the slow messaging and short length limits prevent any real communication. Cell phones have also started getting satellite functionality, but it doesn't work very well, yet, at least as far as I've seen.
I see this march towards internet everywhere all the time as ultimately leading to expectations of connectivity, even in the most remote places–then "will you have made camp by 6pm on Tuesday? If so can you join this quick call?" becomes a real question people feel entitled to ask, notifications start coming through when you turn it on to check the weather, "I'm going back to my tent to check a few emails before bed" might be something you hear around the campfire...
