One of the first things Mary Gundel told us about her childhood was that the Florida foster care system left her with a persistent sense that she was invisible. "Nobody cared, nobody wanted me," she said. Pregnant at 16, then again at 18, and with a third child diagnosed with autism a little while after that, Mary and her husband worked many low wage jobs on opposite schedules so someone could always be home with the kids. But despite feeling unseen, Mary told me story after story about how she changed the lives of her coworkers and loved ones, from taking in a friend's kid, to staying late at the register when a coworker called out, no questions asked.

These sorts of stories might have stayed confined to Mary's small Tampa network had she not become an overnight TikTok celebrity. Her viral moment? A 6-part series documenting her day-to-day frustrations managing a Dollar General, one of America's largest convenience stores, where she worked for three and half years. We talked about what led her to speak out about working conditions on social media, getting fired, and igniting a national workers’ movement. Invisible no more, Mary concedes, “They’re listening to me now!”
