Union Voice/Readers Write: “Fat or “Fair” promotion?

“I checked on YouTube, and it also quotes Dolly Parton (in her song "9 To 5") as saying ‘fat promotion,’ (Labor Quote, 1/29), but I'm pretty sure she's saying ‘fair’ promotion,” writes Paul McKenna. “Doesn't ‘fair’ promotion make more sense?"
It does indeed. Although Lyrics.com has the line as “fat promotion” the more authoritative Genius lyrics site says "9 to 5, for service and devotion/You would think that I/Would deserve a fair promotion". Check it out for yourself in the video below.
