Thanks every one for your support!

As I was leaving the office today, the 3 of them came in to talk to me. They apologized for their rudeness and disrespectful attitudes. They assured me it will not happen again.

I thanked them for the maturity to apologize. For now I consider the issue resolved. I have already spoken to the DM about getting some sensitivity training for the office, because it's needed on many levels. So I'll follow up with that on Monday

As for the other 2 women in my office: One is in her 50's and is quite rude. I often have to say things like "let's clean it up a little." to her.

The other one is in her early 20's and doesn't tend to handle things effectively.

Thanks again for the suggestions and support.
