Looking for another job? One author suggests you shouldn’t use any resources at work. Get a private e-mail account if you don’t have one and field calls on a cell phone.
Personally, I like the idea about a private e-mail account and I would certainly avoid using a fax at work; but I’m not sure it is necessary to avoid your work phone. Cell phones don’t always give the greatest reception and when you are trying to build rapport with someone you don’t know, a land line makes a better impression. Also, it seems fairly improbable that an employer would monitor phone calls.
