Not at all. I feel exactly the same way. I'm also introverted, and to me "relationship building" in a corporate context often feels really contrived.

I want to bring as much value as possible to my employer, and I don't feel like I generate value by having 1:1s for the sake of having 1:1s. I jump through the hoop though, because I want a promotion and I'm concerned that I won't get one if I don't fit the norm.
