It’s been five years since one of Silicon Valley’s most powerful female executives told women to take ownership of their careers, work harder, and demand more. Sheryl Sandberg’s New York Times bestseller, Lean In, opened an important dialogue about women in the workplace—but there was one major problem: It left out women of color—and the unique challenges and obstacles they face.

Sandberg has since acknowledged pay disparities with white women and the ghastly underrepresentation of women of color in the C-suite—and used her LeanIn.org foundation to work with the National Urban League and others to bring attention to the gap. But despite her best intentions, her efforts have not been met with much progress, leaving more women of color to lean out for a chance at entrepreneurship, where they can pay themselves, be leaders, and create impact in ways corporate America does not offer. In 2018 alone, there are 2.1 million Latina and 2.4 million African-American women-owned businesses—representing 172% and 164% growth, respectively, over a decade, according to the 2018 State of Women-Owned Business Report.

Where Lean In fell short, critics say, is its failure to acknowledge systemic barriers that no amount of leaning in can tear down. Imagine having to decide whether to use your real name or shorten it to make it ethnically ambiguous, or easier to pronounce. Minda Harts, the founder of The Memo, a digital career education platform dedicated to helping women of color climb the corporate ladder, knows this dilemma. She was born Yassminda Harts and felt the need to shorten it.

“I had to make people in the workplace feel comfortable with how I show up to work. So, through the years, that’s been beneficial on my career trajectory, but it hinders who I was able to be in the workplace, and we have to show up and choose which route we’re going to go to make others feel comfortable,” she shares.

When Lean In was published, “I didn’t see myself in the book, and I wasn’t represented, but what [Sandberg] did do is leave the door open for us to now talk about why this didn’t work for [women of color],” explains Harts, who will be teaching a course next semester at New York University’s Robert F. Wagner Graduate School of Public Service called Leading Diverse Talent.

“It was heavily skewed toward a white woman’s experience in the workplace. Women of color and working-class women have been leaning in since day one, and when you have systemic systems in place that are not set up to advance people of color—women of color in particular—then it’s hard to lean in when you’re invisible,” says Harts.
