If you need the job, don't confront her with the question "What did you mean?". She might tell you and that could be a problem. Those that said she is concealing something, may be right. I do suggest, however, like I said, if you need this job, is to let her know you will try to become more of a "team" player. Let her know,also, that any suggestions would help.In other words, kiss ass! Hey, maybe thats what she means by "not a team player".
This is a serious suggestion.
