To Caitlin Roberts, there’s no such thing as a “man’s job.” Even while pregnant, she hauled batteries and helped fix cars at John Roberts Toyota, a John Roberts Auto Group dealership in Manchester, Tenn. While coworkers looked on astonished, for Roberts, it was simply routine. Raised by father and dealer John Roberts, who constantly encouraged her to defy gender norms, she wasn’t afraid to shatter the glass ceiling in the automotive industry.
