I work in the HQ office of a major company, there is a few thousand people working here and most are women. I would have to say C or D for sure. I have went with friends when they decided to settle things with rival women. Only seen 1 or 2 co worker fights, the others was just friends from working catfighting other women. They would meet at private home with only a few friends there. No one tried to talk them out of fighting, as it was known both wanted to settle things in this matter. No one broke them up or got involved once they started, they just let the two women involved settle it. If it would have got out of control, I'm sure it would have been stopped, but none went that far. These wasn't trained fighters, they was office women, moms and wives. Mostly inexperienced fighters other than maybe a couple school catfights over the years.
