I do not want to teach the senior official of a company a cellular phone.

I do not want to teach the senior official of a company a cellular phone.It has one cellular phone in one person now.May you teach the senior official of a company a cellular phone? .It investigated by the Internet.It was answered that 40 percent or more of people did not want to teach as a result.It feels conveniently that it can contact at any time.However, at work, it may become pain conversely.I want to distinguish the time of work, and OFF.Many such opinions were seen.
The postscript of edit.I understand this feeling.It is fresh today.It is such a morning.Let's do our best vigorously.Thank you.
