Serena celebrates International Women's Day

• Serena celebrates IWD. Today is International Women's Day. Are you feeling festive? You should. It's an occasion to celebrate the achievements of women, and to call for even more action on gender equality. Fortune has a deep line-up of stories to commemorate the day, as you'll see below, but we're kicking things off with a word from someone who's certainly racked up a lengthy list of achievements—on and off the court: Serena Williams, the tennis icon and board member of SurveyMonkey and Poshmark, is marking IWD with an op-ed for Fortune. Here's a snippet:

Today, March 8th, marks International Women's Day, a day dedicated to celebrating women's achievements across social, economic, cultural and political spheres. Every year, I look at IWD as a reinvigorated call to action: together, we can accelerate global efforts to reach true gender parity.

In our fast-paced world, expectations for women continue to rise, as do workplace demands and, unfortunately, double standards. Navigating it all is especially tough for working moms, myself included—I feel the pressure both on and off the court. Even with all the resources I'm incredibly blessed to have, motherhood comes with so many unexpected challenges, especially when it's time to go back to work.

As a board member of SurveyMonkey, I encouraged the company to conduct a pair of surveys that would help us better understand the adversity American women face when it comes to balancing their professional and personal lives. One focuses on the experiences of working parents, while the other delves into those of all women in the workforce. After reviewing the results, one thing is clear: many of us are facing strikingly similar challenges.

For starters, our data show that women are four times more likely to say they provide more childcare than their male partner—pulling a double shift at work and home. This contributes to the fact that nearly half of women say they have sacrificed career goals for their family. I know I did. More than half of moms feel guilty leaving their children to go to work and a third say their job makes it challenging to do the things they want and need to do for their family. Forget the cliche of ‘having it all,' the reality is, women are trying to do it all.

The surveys also revealed that there's a 10 percentage point difference in the share of men vs. the share of women who say they are "extremely" or "very" comfortable taking risks to advance their careers. This is something that's really important for me to emphasize: it's OK to take a risk for your professional growth. You have to make yourself uncomfortable and push your limits to find out what you are truly capable of accomplishing. Whether you're a top executive, talented artist or passionate athlete, the risk is always yours to take.

Williams goes on to advocate for women's support for other women, the break down of sexist double standards, and the end of penalties for new moms returning to work. You can read her entire op-ed here, but I'll leave you with her rousing rallying cry: "We must band together and fight for what's fair." Fortune
