re: Do you use sir and ma'am with older coworkers?

I don't all the time. There's a degree of familiarity where using it becomes uncomfortable. Some older people hate it. I've really been thinking about when I use it, and it's more of gut feeling when to use it than anything else for me.

It's odd because I was never raised up using any of that. I just kinda picked it up. My father is vehemently against it. "Use their first name," and will lecture someone if he's called sir.
