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.
“I’m sure you’re perfectly nice as a friend, but I’m not looking for a friend. I like to keep my work and private life separate, and I’ll thank you to do the same around me. Don’t think I dislike you; but for me, personal chat is an unwelcome distraction.”
Don’t say it, send it in an email.
Carry it printed on a sign behind your back until he pops up, then whip it out after the first question. Then walk away after he’s read it, while conspicuously taking handwritten notes and looking back over your shoulder.
This is the best answer. Not that you even owe them this much of an explanation. But it provides enough detail to satisfy them and succinctly tells them in corporate language to fuck right off.
