A Hollywood producer is learning the hard way that Mila Kunis does not appreciate being referred to as “Ashton’s wife and baby momma!!!” Kunis’s production company had signed on to work with an unnamed producer on an upcoming TV show, but when Kunis found out how the Hollywood exec described her in an email, she called off the deal.

In an open letter posted on Medium, Kunis writes, “Throughout my career, there have been moments when I have been insulted, sidelined, paid less, creatively ignored, and otherwise diminished based on my gender. And always, I tried to give people the benefit of the doubt; maybe they knew more, maybe they had more experience, maybe there was something I was missing. I taught myself that to succeed as a woman in this industry I had to play by the rules of the boy’s club. But the older I got and the longer I worked in this industry, the more I realized that it’s bullshit! And, worse, that I was complicit in allowing it to happen.”

That complicity is over. After years of putting up with Hollywood’s sexism, Mila is taking a stand.

“I’m done compromising; even more so I’m done with being compromised. So from this point forward, when I am confronted with one of these comments, subtle or overt, I will address them head on; I will stop in the moment and do my best to educate. I cannot guarantee that my objections will be taken to heart, but at least now I am part of creating an environment where there is the opportunity for growth. And if my comments fall on deaf ears, I will choose to walk away.”

In the letter, Mila explains how workplace sexism isn’t just a problem in Hollywood and acknowledges that not every woman is in a position to walk away from work. If you’re living paycheck to paycheck, you probably won’t risk confronting coworkers or supervisors about their sexist comments. “If this is happening to me, it is happening more aggressively to women everywhere. I am fortunate that I have reached a place that I can stop compromising and stand my ground, without fearing how I will put food on my table. I am also fortunate that I have the platform to talk about this experience in the hope of bringing one more voice to the conversation so that women in the workplace feel a little less alone and more able to push back for themselves.”
