the other females would superficially treat the ENTJ in a very nice way. Then, once she had her backed turned, they would say things like "Let's just ignore her next time she comes!". The worse being, that, once the ENTJ tried to confront them openly, they would deny everything and, worse, would then accuse the ENTJ of being mean and aggressive. When I asked the girls why they were doing that, one replied: "There's no use in creating needless conflict. Plus, come on... she's really a bitch, she deserves it".
I hate that sort of thing.
My daughter is in third grade and has already had to deal with it. She said the other week a group of girls would come nearby and talk about her... and every time she tried to join their group, they would leave, just far enough that she could not be part of the group, and then look at her and laugh. (She's a tough cookie, though -- she befriends the other girls who have been shunned, and she's intruded on their group and joined their conversations whether they liked it or not.)What do you think about these behaviors and do you have any anecdotes in mind?
I would really so much hope that those behaviors would be left behind in childhood, instead of being practiced by adults. It happens when people are territorial as well, like in churches or other organizations, where there is a "self-ordained privileged" group. People who just want to bolster their own importance by ostracizing others.
It definitely seems possible that your friend was being ostracized because of her strong personality and because she was not acting in line with the other women at her company -- i.e., breaking the social code.
