Right now I am on vacation, my work phone stays at home with an empty battery.
They still have my private number if it is an absolute disaster at work and they need my help, but untill sunday evening I won’t even charge my work phone, let alone check it for messages/calls.
Work apps stay on the work phone, the ONLY exception to that rule I will ever make is work MFA apps.
But I’d sooner get a new separate phone for that if I don’t get a company phone.
