Jan Levinson (formerly Jan Levinson-Gould) is played by Melora Hardin. She became known as Michael Scott's superior at the New York City corporate headquarters of Dunder Mifflin, a paper company.
At the onset, Jan is presented as a no-nonsense manager and strong female role model, but she eventually devolves into a total mess, getting divorced, then fired, then - after beginning an on-again, off-again romance with Michael - letting her half-crazy, awkward, neurotic side come through in a big way. What will Jan do next?
Jan: All right, well are you gonna take care of this?
Jan: What did I tell you about "yeppers?"
Michael: I don't... remember.
Jan: I told you not to say it. Do you remember that?
Michael: Here's the thing. Chili's is the new golf course. It's where business happens. Small Business Man Magazine.
Jan: It said that?
Michael: It will. I sent it in. Letter to the editor.
