Trouble with a corker

Now I’m 29 years old and I have many jobs. I am working with a difficult co-worker. Who I feel is trying to intimidate me. I don’t do well with those type of people because I am no punk. But this is my job. So she just started working mornings with me and she is not really doing much work but answering phones and being on her cellphone. Then I come back and have to do all the work that she didn’t do. Plus she is loud and obnoxious . I can’t hear my guest when I’m on the phone. One time she cursed so loud, she didn’t know I was on the phone and my guest heard her. I didn’t say nothing but I definitely wanted to ask for advice to one of my managers.

And she wanted to step in and handle it.

I wanted to but she thought it would be appropriate for the managers to do that. Am I wrong for going to my managers? This girl act like she don’t hear or want to talk to anybody. Got the nerve to ask me to turn my music down (which is not even that loud, no one complained about it but her lol) but she is the loudest one in the room. Her voice Carrie’s. But if someone says something to her , it’s a problem . What y’all think?
