During the event Duncan discussed the challenges of working in news environments with predominantly white directors and producers.[8] She has also spoken publicly about the gender pay gap. In a 2019 interview Duncan shared that as a new professional she "didn’t realize negotiating was something I could even consider," and has since shifted to discussing salary and negotiating with women colleagues.[9] The experiences of women in media, including their careers and personal lives, is a central theme of her podcast Media Girlfriends.[3][10][11] It launched in 2016 and has evolved to include in-person discussion panels, mentoring, and the funding of scholarships for women and non-binary journalism students.[12]
