How do I work with a colleague who has attitude, won’t say hi and is extremely rude and moody?

Update: She’s recently returned from maternity leave, working 2 days week.
I briefly said “hi mary, welcome back” as i left my shift and she wAlked passed me to  start her shift, she fake said “hi” and kept chatting to the woman she walked in with
I was polite..
