Do you have any phrases to stop disrespect at work?

A coworker lower on the totem pole has been very rude and condescending towards me. Calling me missy, dumping work that falls under her job description onto me, huffing and puffing any time anyone assigns her a task. And I have no idea how to respond other than ignore her 90% of the time.

What is some good phrases that are still kind but express she can’t call me names or act the way she does?
