When I communicate with people on business matters, I try to follow a simple set of common sense (at least to me) rules. - If I have something that requires an immediate answer, I call people. I do not expect them to check their e-mail every 60 seconds 24 hours a day. - If I have something that's not time critical, I either send e-mail, or call during business hours, excluding lunch break. I am also familiar with the concept of time zones. - I call people from a phone number they can call back and reach me. - If I call someone and get his voice mail, I listen to the message. It often tells you where to find the person you called or someone else who can help you. - If I need to leave a voice message, I tell my name, my company, and how to call me back. I do not present my life story in a 10-minute monologue. Do you think my set of rules is unreasonable?
