The term “gender inequality” sounds more like 1913 than 2013, yet women today still make 80 cents to every dollar a man earns. Why is that? Why are women afraid to ask for a raise? Why aren’t there more women leaders? And why don’t women band together and help each other more often? Facebook COO Sheryl Sandberg is answering those questions in her new book, Lean In.

“Success and likeability are positively correlated for men and negatively correlated for women.”-Sheryl Sandberg

A common dilemma women face is balancing the demands of work with the demands of motherhood. Sheryl Sandberg has a seven-year-old, a five-year-old, and a $60 billion company to run.

“That pay equity is a crisis we need to address.”-Sheryl Sandberg

@katiecouric @katieshow I don’t think women can have it all at the same time. I’m a lawyer who decided to work part-time when I had kids.

Women make up more than half of the workforce, but are just four percent of Fortune 500 CEOs. How can more women claim the corner office? Christine Day knows the struggles of climbing the corporate ladder. She spent 20 years at Starbucks before jumping to Lululemon, the athletic apparel company she eventually became the CEO of in 2008.

“We expect to be picked as opposed to saying what I want.” -Christine Day

@christineday, a CEO and former Starbucks exec, is most impressive on @katiecouric Great discussion.

The fear of being labeled “aggressive” or “pushy” is holding a lot of women back and keeping them from getting what they want in the workplace. Linda Babcock is a professor of economics at Carnegie Mellon and the author of Women Don’t Ask: Negotiation and the Gender Divide. Hannah Riley Bowles is an associate professor at the Harvard Kennedy School of Government.

“Our society has told us to hold back when it’s for ourselves.” -Linda Babcock

Thank you for this wonderful episode on Women in the Workplace @katiecouric.

Women have made great strides, but the startling truth is they are still making just 77 cents to every man’s dollar. Evelyn Murphy is president of The WAGE Project, a national organization to end wage discrimination against working women. She joins Katie, along with Trish Fontanilla, Devona Cartier, and Chenita Daughtery, who all signed up for a workshop to learn how to ask for a raise.

“Stay away from the personal stuff.” -Evelyn Murphy

Right now there are 98 women in Congress, 20 in the Senate and 78 in the House. While that’s a record number, it only represents 18% of Congress. Kirsten Gillibrand is a senator from New York working to give more women a voice in politics.

“We need affordable daycare.” -Kirsten Gillibrand

Since it is not every day we have someone like Sheryl Sandberg in the studio giving career advice, Katie decided to have the Facebook COO answer some of your Twitter and Facebook questions.

“We have to not call our daughters bossy.” -Sheryl Sandberg

@katiecouric I was called ‘bossy’ and even my mom referred to me ‘bossy’ as a child! #boysarebossytoo
