Once Michael, Pam, and Ryan all return to Dunder Mifflin from the Michael Scott Paper Company, there's a lot of hostility amongst the sales staff due to Pam and Ryan keeping the clients they stole from the Dunder Mifflin sales team. Phyllis is by far the worst of the worst, especially to Pam. She's super aggresive towards Pam and even goes so far as to call her a secretary when she knows that's not her job anymore. Phyllis, Pam has established herself as a salesperson. She took a leap and went for what she wanted, and she got it! But you know, it's OK to belittle a co-worker if they're pretty, right? WRONG.
