When one team gets credit for your analysis, and you get nothing.
A situation beneficial to all parties involved. The mythical outcome where both sides are happy, but usually one side gets screwed.

"We’re automating the reports, so it’s a win-win! Except now, I have to explain to everyone how the automation works."
