Yahoo’s new CEO Marissa Mayer just joined the ranks of a very small number of women at the top of Fortune 500 companies (19, to be exact). And at six months pregnant, she is a visible and public reminder of the challenge that accompanies women’s (and men’s) attempts to achieve work/life balance. Knoxville’s WBIR Channel 10 invited me to reflect on what Mayer’s situation says about gender, family, and the workplace in the U.S. today.
