I have a company supplied cell phone. I could use it for personal use, but I don't. When I leave the house in the morning it goes on my belt and when I return home in the afternoon it comes off. I don't answer it 75% of the time regardless of who is calling, be it my boss, a customer or the dispatch office. I consider it an annoyance.
BTW, at home I only answer the phone, landline, about 10% of the time unless I'm expecting a call. Yes, I don't particularly care for phones period because I don't feel a need to be connected to the world in that way. If it's good news I will find out soon enough and if it's bad news I will find out too soon whether I answer the phone or not.
