Can't get it off their....work phones.
Probably also can't get their work email and Teams and whatever else is on there off their work phones. Because they're work phones. If you're not on, put your work phone in a shoe box far from where you sit and hang out. faraday bag, even better.
Wired, c'mon. Only a genuine idiot would use a work phone as a personal phone. Anyone complaining about this gets what they deserve.
