As an IT I kinda have to. Lot of mails, occasional calls outside of my shift and I sometimes even have to log in from home to solve some issues. I need to have certain info downloaded on my personal mobile phone for ease of use, inside of the company too because I can check my phone in 5 seconds as opposed to necessarily carrying my laptop around or logging with my profile in to access my personal files on the server. On the other hand I don't quite have enough workload and phone calls with clients/sellers that I require a work phone, so it's a choice and a bit of a necessity as well. I'm not a fan of having the mail, in particular, but I also get the logs for the backups, get notifications for power outages and so on, so even when the company is closed I need to keep an eye one way or another. Luckily enough, in the 30 months or so I've been here I logged in from home or went in on a short notice less than 10 times, plus about that many short phone calls where I managed to guide the other person through voice alone.
In short, I keep some work stuff on my personal phone. Not a huge fan of it, but it's often for my own convenience and seldom I have to use it outside of the workplace, so it's not that bad ultimately. I'm not the kind of person who still regularly has work-related phone calls at home at 10PM, and I certainly don't miss being in that role. More money is always exciting but if I can't have time to enjoy myself why bother? I'm fine like this.
