What is the proper way to address your boss?
user
The proper way to address your boss is “Mr. or Ms. Last Name.” The proper way to address a coworker is “Mr., Mrs., or Ms. First Name.” It is also appropriate to address a stranger as “Sir” or “Ma’am.”

Uh oh.  I’m not sure what you mean by “proper”, and I don’t want to tell you what to do, but there is an issue at hand!  Is it a matter of addressing your boss respectfully, or of speaking to your boss in a way that shows your respect?
