I wanted to get an outside insight to my situation with a co worker(A). Just 5 months ago a co worker git hired. At first everything was okay and I got along with her great but I did feel a sort of forced vibe from her. I ignored it and just continued making sure work for her was easy. I would try and show her various things so she can get the hang of it. Well fast forward a few weeks and I noticed this persistent issue of her not doing her job. Don't get me wrong she was great with customers but when it came to doing things outside of customer service you pretty much had to push her to do it. If you didn't push her she would just sit down and not do anything. I brought it up to my co workers and they agreed that she doesn't do anything unless you tell her but later one we realize she seems to have an issue with female coworkers. So me and another co worker(B) realized and agreed that co worker A doesn't seem to like us since we are women. I feel like I gave her many opportunities and her attitude was still there. I spoke to my manager and told him the things she does and said I have to be more assertive with her. Well on April the manager went on vacation and on the first day he was gone I was closing with co worker A. As soon as I came in she asked if she could leave early. I assumed 1hr to 30 mins before he shift ended but jo she wanted to leave 4 hours before her shift ended pretty much leaving me by my self for 3 hours. I spoke with co worker B and she agreed that was too early and not possible. I then told co worker A "hey so I'm sorry but I don't think I can let you leave that early but if it's not busy 1 hour before closing then you can leave then. I'll try to make it possible to leave 1 hours before." She didn't respond and just ignored me. The reason to why she wanted to leave early, well her family was coming into town along with her baby daddy and wanted to meet up with them sooner. Now if it was a real emergency then yeah I would've let her leave early but meeting family for me is not an emergency. Fast forward to an hour later she was using her phine in front of a customer, which is an issue I brought up to the manager and spoke to her before, the customer complained. I apologized to the customer and said I would speak to her. Before speaking to co worker A, I let co worker B know what happened and agreed I should talk to her. I waited till co worker A was alone to speak to her so she wouldn't feel like I was putting her on the spot. The conversation went as follows:

Me: Hey, can I talk to you real quick Coworker A: sure Me: so the customer that you were helping earlier complained that u were using your phine in front of her when u where helping her. She felt as if u weren't paying attention to her as a customer. So I just want to let you know try not to use it infront of a customer. If u really have to step aside, you know to avoid any issues. Coworker A : well my baby is traveling so I have to be on my phine all day making sure he's okay. Plus I spoke to the manager and he said it was okay (B.S)

Before I can continue to explain she goes off with an attitude I simply decided to walk away because I know of I stayed there I could easily make her break down and cry and I would be the one in trouble. I told coworker B and she was confused by co workers A attitude over a simple request.

Fast forward to my lunch and all the sudden she felt "sick and had to go home early which pretty much left me closing alone and working alone for the next 3 hours after co worker B left.

Fast forward to the manager coming back and I told him hands down everything that happened and told him I refuse to close with someone that will carry an attitude over every little thing that she is told to do. He said he won't have me closing with her as much hut I told him "no I don't want to be closing with her at all period"

He spoke to her and told me and the other coworkers that she feels like we don't help her out and the reason she refuses to do things is because she doesn't know. This is coming from a 21 year old mom who I guess can't use her mouth to communicate. I told my manager that's b.s because when ever I try to show her things she doesn't know she either walks away or give an attitude to why she can't do it. I've also experienced her telling me well idk how to do this and right when I'm about to show her she magically knows how to. The issue isn't she doesn't know the issue is she doesn't want to work.

That was 1 month ago. Today I noticed that I am scheduled to close with her again in the next week coming up. I talk to my manager and said if I can either leave early that day or just not close with her he said no because he doesn't feel comfortable her closing yet and said to just try and move on from what happened and give it another chance. I honestly feel forced to close with her when I've countless of times have made it clear I am not comfortable closing. I told him I will close but If she gives me the slightest bit of attitude I'm walking out on the spot. He said to atleast try and stay to close since hasn't closed alone and I told him sorry but no at this point if the company isn't concerned with my issues then I won't be concerned about there's.

Should I take this up to HR or should I just give it another chance. I'm literally having anxiety knowing I am closing with her next week and Idk how it will go but I have a feeling it won't go well.
