If I was expected to be available all the time, you can be damned sure I would have expected to be paid by the hour for that.
That being said, answering anything work related outside of work, unless they are your truly close friends is lame and considered a character weakness, to be abused. And don't expect any extra bonus points for that.
Having a good private (aka actual) life you are willing to defend ain't a sign of weakness, in contrary.
Mine just stays on my desk when working and goes to a drawer when not. It is basically just a 2FA device. There is nothing to lug around.
And that’s fair. But I don’t want that on my personal devices. It’s literal spyware.
If work wants that level of control on my phone, they can just give me a phone they own outright. I’ll give it back when I’m done working there.
Seriously, it’s a huge mistake to mix personal and professional data on any device. Too many risks I want nothing to do with.
When I was younger I would answer calls and emails outside of work hours, because I wanted to be a Good Employee, but it's a huge mistake because management (and sometimes coworkers) will exploit it and after a while expect you to do it. Set hard boundaries immediately.
You absolutely want hard physical separation between personal devices and company-controlled business devices. That means two phones and never allow control to cross those boundaries.
After work, I put my work phone away. I have been in this industry for over a decade and I wouldn’t have it any other way.
I will never let an employer steal time away from my family again. Especially now that they want us all to RTO. Office time is theirs, home time is mine.
Makes it real easy to control how available I am to different groups of people.
Anyone who cares about privacy and control of their personal life.
