She is a good coworker, meaning she knows her duties and has ample experience.
She is also a gossip and a person that will rant when somebody doesn’t greet her the way she believes she deserves to be greeted, or about how a coworker or manager wasn’t friendly to her. It’s both what she says and how she says it, like she was hurt.
I still don’t know if what she wants is that everyone stops doing their jobs when she enters the workplace to give her attention, because otherwise, apparently, people hate her. She is also very pretty. Not that I’d want a relationship with her, because this trait is very off putting.
I’ve already heard her saying I’m not friendly and I don’t know who should I react. I think it’s ridiculous to start giving her attention to keep the peace because I have things to do that pay my bills and it would be very draining, I cannot fake interest in things that bore me. I don’t understand why we can’t just do our jobs and go home.
Lots of bigger workplaces actually have some sort of private organisation you can basically vent to and ask advice from, so that might be a good idea place to start. The whole point of these is that they’re totally anonymous, so you basically cannot get any blowback from talking to them.
You can also speak to your boss if you have a good relationship with them. Just explain as neutrally as possible that you’re finding it a little difficult to work with this particular co-worker. You don’t need to ask them to do anything specific, just be honest that it’s difficult. They might be able to either bring it up with your co-worker (keeping you anonymous, of course), that other people are finding their behaviour offputting, or just arrange it so that you don’t have to work together.
