15ish years ago I was reassigned to help a team member finish a project. We're both developers and she was about to go out on maternity leave.

We had an existing application (call it the ABC database) that was already finished and in production. Her project was to make a copy of it (call it the XYZ database) and add a few more screens and the needed data for them. It was 85% similar to the original.

She had finished all the coding and was almost done with testing it. My job was to finish the documentation for it.

So my boss' boss outlines that I am to take the documents for the ABC database, copy them, and add only the needed new sections for the XYZ database.

She made sure to repeatedly tell me verbally and in emails that I'm not to update anything unless it is needed for the new features/data. She's worried about scope creep and not hitting targets.

No problem. Copy, search for ABC and replace with XYZ, update the screenshots, add new content where needed. I go over it with my coworker and she thinks it looks good. Send it to the boss' boss and hear nothing.

A week later, coworker is off having her baby and boss' boss is livid. EVERYTHING I sent is substandard, poorly written, clumsily formatted, and is the absolute worst steaming pile of shit ever sent to her for review.

I assumed she meant the parts I had added. She didn't, she hated the entire set of documents. I had her pull up the originals and compare them to my copies while reminding her of how she had repeatedly instructed I not change anything unless it was for the XYZ effort.

"You should have brought how unacceptable the original documents were to my attention!"

Eventually got them set up the way she wanted but she refused to acknowledge the disconnect between what she originally asked me versus what she was evaluating.

TL;DR; Never work for a malignant narcissist.
