It’s different in my own situation (I don’t have a boss) but would I be employed I would not mix work and personal. Ever. Phone, friendship, or whatever else as there is a too high probability some shit will happen.
I would have my own phone and next to it the job would provide me another one with whatever shitty apps they require me to use, if they rely want me to use it. And I would turn that bastard off the moment my work day is finished (aka the moment they stop giving me money in exchange of my time).
Exactly like I would not use my own computer for work. It’s mine.
Yep, French, it reads ‘Les bons comptes font les bons amis’.
