TRANSCRIPTION

“Female hostility. I always get the question. Sometimes people say that the women in the workplace are worse than the men. I don’t know whether that’s true or not, but I will say that when women don’t support other women, it hurts us more. We expect solidarity from our female colleagues.”

That was Dr. Amy Diehl, co-author of the book Glass Walls: Shattering the Six Gender Bias Barriers Still Holding Women Back at Work. In the next 45 minutes, we’re going beyond the glass ceiling and glass cliffs. You’re going to learn what those six glass walls are, how they manifest at work, and what we can do about them. Especially in the context of communication, we’ll explore the power of labeling these barriers and talking about them.

We all witness these glass walls at work. Whether you’re a woman directly affected, an ally observing them, or a leader with the power to influence change, this episode is for you.

Let’s be clear: this isn’t about complaining. This is about using real research to identify, label, and discuss gender bias.

Welcome to the Talk About Talk podcast. If you’re a returning listener, welcome back. If you’re new, let me introduce myself. I’m Dr. Andrea Wojnicki. Please call me Andrea. I’m an executive communication coach at Talk About Talk. You can learn more about me at talkabouttalk.com. While you’re there, I encourage you to sign up for my email newsletter.

I help leaders improve their communication: presentation skills, executive presence, precision, and personal branding.

All of these skills are hard enough without the additional challenge of gender bias.

Recently I read Glass Walls by Dr. Amy Diehl and Dr. Leanne Dzubinski. From a communication perspective, I saw insights that I knew would resonate with you. So I reached out to Amy, and here we are.

Are You A Charlotte?

Are You A Charlotte?

In 1997, actress Kristin Davis’ life was forever changed when she took on the role of Charlotte York in Sex and the City. As we watched Carrie, Samantha, Miranda and Charlotte navigate relationships in NYC, the show helped push once unacceptable conversation topics out of the shadows and altered the narrative around women and sex. We all saw ourselves in them as they searched for fulfillment in life, sex and friendships. Now, Kristin Davis wants to connect with you, the fans, and share untold stories and all the behind the scenes. Together, with Kristin and special guests, what will begin with Sex and the City will evolve into talks about themes that are still so relevant today. "Are you a Charlotte?" is much more than just rewatching this beloved show, it brings the past and the present together as we talk with heart, humor and of course some optimism.
