A while back, when Facebook CEO Sheryl Sandberg first published her book, Lean In, I argued that the concept of using social media to bring women together in consciousness raising groups was terrific, but that Sandberg’s formulation was flawed. I’m excited to read an article in today’s Boston Globe that a domestic worker fighting to unionize at an area hotel has challenged Sandberg to lean into her cause. The only way we’ll make real change happen in this country is to work across lines of difference (race, class, gender, ethnicity, religion). Real change doesn’t just improve some peoples’ lives. It has a positive effect on everybody.
