It’s not a Competition; it’s a Climb. So Stop Fighting Other Women to Get Ahead
Working Girl, 1988. It's a beloved little comedy centering on Tess McGill (Melanie Griffith), new to the cutthroat business world and secretary to Katharine Parker (Sigourney Weaver). When Katherine steals a tip from Tess to further ascend the corporate ladder, Tess "borrows" Katherine's identity to regain what is rightfully hers. The movie closes with Tess winning the showdown while a scorned Katherine fades into irrelevance with her tail between her legs. Oh, and Tess also manages to steal Katherine's boyfriend along the way.
