How to deal with a toxic coworker?
I really don't have anyone to tell the story to but I've known my coworker for a few months. We used to work at a pediatric clinic that was overpacked and had a lot of drama with many different coworkers and it was annoying tbh. Anyways ever since I was moved into the front office to answer phone calls. (I'll call her Jessica f32) Jessica helped a few other coworkers and me (f21). I've become friends with her due to another close friend from high school. We would hang out together for lunch and talk about stuff, we all got along but ever since I was observing her, she'd get along with everyone. I really didn't like my job there because of how toxic it was and how one of the supervisors threatened my life because I got a new car. She was talking with the supervisor which made me feel uncomfortable and all. She'd complimented my appearance and my jewelry. I had a red Tory Burch bracelet that my mom gifted me and Jessica asked where I got it and that shed buy herself one.
since I found another job at an urgent care. I've made a mistake in bringing her into it. Its a new urgent care in a small town but she's been bragging about me to the manager and providers. I was barely new in the front office and was trying my best to verify insurance. Rudely, she would tell me how many mistakes she's noticed. How after procedures I forget a few things. Like I said everything was new for her and me, but she was setting a dominance in the field like she owns the place and wants to be a manager. Shed flirt with the manager even though he's a married man and an older man. Because of her complaining it made me look terrible, I'd try my best to improve and ask for help but she wasn't willing to help at all. I've asked if she could scan some patient information and she sent me a text saying "I'm no longer going to do your job. So don't ask for my help." I was confused because I didn't know what I did?
Now, she still complains about me and still wants me fired, I was almost about to get fired btw but I told the manager my part of the story. She's thrown tantrums and left unprofessionally, but let me work the 12-hour shift several times (I have no problem with it). She then complains about not having enough hours. I want to ask why she's bothered by me but I don't want to cause trouble or drama. Today we lost several pieces of our equipment and I've told her "Hey, we lost the key to our quest box" She replied, "I didn't lose it, so I don't know"
I never assumed she stole it, I've told several providers about the lost key just for a heads up. Our manager has a spare key but doesn't trust us anymore with it. I'm so confused why she is like this... I've told my parents about her behavior but it's been 9 months of her acting like this. Any advice, should I just ignore her? I honestly don't want to work with someone who has a grudge against me.
