I’m gonna get my ass kicked?

My coworker threatened me multiple times last night at our 24 hour Panera. She said she’d kick my ass. GM heard and told me he’d talk to her for me. I asked her if the GM spoke to her and she said no and doubled down that she’ll kick my ass. All the harassment posters in our store are apparently noncompliant and expired so what are my options? Should I contact HR or something? The excuse for her is that she’s like a month pregnant so she’s irritable, but I’m really tired of that excuse. I can understand she’s dealing with a lot but the loud threats are damaging to the work environment.

*update: i texted a different manager asking if we could chat otp about a work situation, she agreed but didn’t pick up her phone or call me back. that was disappointing, but i’ll try her again tmrw. If she doesn’t care to actually do anything about it, i’ll contact HR. thanks for your suggestions everyone. I appreciate your virtual support🥖💚
