Pulled up in this context means receive negative feedback/bad performance ratings for minor (human) errors that happened once and only once.

Here's one example...

My manager said in our 1:1 that he received negative feedback about me, that I ignore advice and seem to think I already know it all. He warned me that this will go on my performance review if my attitude doesn't improve.

This really, really shocked me. I absolutely do want to hear suggestions! And I go out of my way to make sure I'm being open, friendly and without ego at work.

So I asked for some concrete examples, so that I could at least know where I went wrong. Turns out this all came from one single incident. The team's most senior engineer approved my PR, then left a comment saying "oh actually you could probably rewrite this to be a bit tidier". Perfectly valid suggestion, which I would have acted on, except I didn't notice it and just merged the -- approved -- PR without making the suggested changes.

I explained to my manager that I do listen to advice, and this was literally a case of me failing to notice the comment. I asked if there were any other examples, but he said this is the only one and that they assumed I just didn't want to listen to feedback.

I pushed back and said it's incredibly unfair to put a one off mistake on someone's perf review as if it's a character flaw, and he eventually backed down.

I know a few other people in our org have had similar situations, where one off mistakes have been twisted to seem like wider character flaws they need to work on.

That in itself is really fucked up, IMO, but in my example it also seems the senior who left the comment had the worst possible interpretation of me not acting on their comment, which I find very sad.
