I go to work to work because I need a paycheck, not to make friends.
Where I am there is a new coworker that to me acts needy (think of Slow Horses’s Struan Loy), tries befriending me, but he invariably asks if everything’s ok. I don’t care about this person’s life.
The first 2 times I didn’t think anything of it, but he asks that every day and it’s becoming tiring.
I feel mobbed and stalked, mobbed because he keeps insinuating there is something wrong with me just because I don’t ask him about his private life and do my job, and stalked, because he is so fixated on me.
going to HR over this seems ridiculous, but I’m starting to hate his voice.
First off, I’m am not seeing really great communication skills coming from your end in your story here.
This is predicting. Or do you actually know he thinks this? The use of ‘insinuating’ sounds like you’re filling in a lot of blank space with your own narrative. Unless he came out and actually said this, private information isn’t necessarily an unspoken agreed upon trade. And if it was that would be a fault on his side.
And Just to get it out of the way: Introvert isn’t where you don’t want to socialize. It’s just a personality trait in how you recharge with or without socializing. Typical introvert would not avoid socializing altogether. They’d socialize and then excuse themselves for a time being. This is of course with healthy preferences of who to socialize with like any average person could have and that is perfectly fine but that isn’t a trait of what makes a person introvert or extrovert. That’s just having standards.
Either way, this just sounds like you have made a choice that this person isn’t for you and you have some unspoken boundaries and expect someone to know your boundaries without telling them. Even if you think you are being clear with social queues this might be a case of miscommunication of what a social queue is for you and what he reads communication(possible) . But I wouldn’t leave that to assumption.
People aren’t mind readers so of it is bothering you this much you could tell him like several others are suggesting.
after that if he doesn’t let up, see HR as that would be harassment at that point.
