I really hate one of my co workers

[GoSmoke]

I work with a girl, let's call her Denise.

Denise has a very bad temper. She yells at everyone, including me, but it seems like the last few times I have worked around her, she has been picking on me. I just started my job a few months ago so I don't know everything, but she screams at me anyway if I do something she doesn't like. I got thrown on the register two days ago and everyone has been really nice to me about the few mistakes I have made, but she has been nothing but abusive and yelled at me yesterday in front of a whole line of customers. I was humiliated and scared she was going to get me fired. She's a department head and could do that if she wanted too.

The store manager and the assistant manager and I get along just fine. In fact, my store manager seems to really like me and has told me a few times that I am doing a great job and thanks me for my all my hard work. I know I work hard, I am so exhausted I have no energy to do anything but eat and sleep outside of work. My immediate supervisor and I get along fine as well. It is just this one department head who seems to have it in for me. I have done nothing to Denise except my very existence seems to piss her off immeasurably.

This is a good job and I love it except for the days Denise works. Is there a way for me to deal with her without getting myself fired? I am hesitant to talk to my store manager because Denise seems like the sort who would slash my tires if I got her into trouble. I know I should say something, but I really don't want to put myself or my job in danger.

Any advice on how to handle this?
