My company gives cell phones to all the managers that are intended to be used only for business. Most people have two cell phones - one for personal reasons and one for work :)

What do you mean about in your own time?

And what about matters requiring extensive discussion that can't be done through email?

Glad to hear it..

If it's business related then fine but if it's personal, no..there is no room for mobiles in the workplace as people take advantage and slack..

You shouldn't text or phone anyone while you or they are at work unless it's an emergency or your in your own time..

Would I be correct in assuming many people overuse their personal phone at your company?

No when I had my company it mobiles were not an issue but I see it now all the time..

Would you use your personal one in work hours?
