Hey,
So I just started at a job where I have a coworker who has begun to make really off-putting comments. Today while I emptied the paper shreds from the shredder into a garbage bin she said “garbage is a man's job”. She makes little digs like that atleast twice per shift; I've been here for about 2.5 weeks now. She also will play random insulting tiktoks off her phone and laughs(I'm not sure if it's her real laugh or not because she literally goes “wuuuhoohahaha” like an evil Disney character lol. And when she was filling out a report about who's on the clock she said outloud she knows our other coworker will be there- implying that she wasn't sure if I would be even though we are fully aware I am scheduled as I agreed to.
She also waits for me to leave before she herself leaves, as if she's trying to prevent me from saying anything to anyone else. And regularly would tell me certain things I can't do but she would then do all of that stuff herself.
A final note is that I had a phone call today where the customer, who was definitely on drugs, tried to lie about some circumstances and his name, so I called him out on it. And when I got off the phone she said “you're trying to get us killed”. And honestly I think it was a projection of her own experiences and maybe that she is not above doing something vindictive if she were called out, herself.
Everything she does feels so shady. And she's in her 40s I think.
How do I bring this up to HR? Or should I ask her what her problem with me is? What is the most mature/responsible/safe approach for me to take?
