There was a super weird alignment at a previous job where the appearances, personalities, and seniority/rank of some of my co-workers matched characters in Dilbert to the T. It was really funny and almost eerie, like Scott Adams was hiding in a cube taking notes.
The VP who "raises issues" reminded me perfectly of someone at a prior workplace.
IIRC he did get a lot of ideas from fans talking about their own workplaces …
Once, for a whole week, every Dilbert cartoon matched something that happened in our office of ~50 people the day before. People started getting freaked out like we were in the Matrix or someone was feeding it to Adams.
