What is the woman mainly complaining about?

M: So, how are things going these days?
W: Couldn’t be worse．Did I tell you I have a new boss? She almost drives me crazy.
M: What does she do?
W: She is so hard to work with．She is so unpleasant and keeps giving a lot of work that she wants done right away．I can’t tell you how exhausted I am when I get home every day．
M: Have you thought of talking to her?
W: I tried once, but it was in vain．She didn’t listen．In fact, she talked for a good five minutes．I couldn’ t even speak．All she talked about was that it was her responsibility to make sure that things didn’t get messed up and that I’d have to learn to work under pressure．She is under the illusion that she’s a good manager.
M: I wonder where she got that idea．Sorry, go on．
W: While we were talking, the phone rang, and she told me something had come up and I should get back to work．How could she be so impolite? She upsets me so much that I’m about to quit．
M：Well, if I were you, I’d think about it carefully. Talk to her again and see if she could understand your feelings before I make any decision．
