Alba, 36, is one of hundreds of women in show business who have come out in support of Time’s Up: a call to action launched on New Year’s Day to bring attention to the idea of combating sexual harassment, assault and inequality in the workplace.
Originally published in the New York Times, the campaign’s accompanying open letter read, “The struggle for women to break in, to rise up the ranks and to simply be heard and acknowledged in male-dominated workplaces must end; time’s up on this impenetrable monopoly.”
On Sunday, most attendees at the Golden Globes wore black as a symbol of solidarity — many who were initial signers of the letter, including Eva Longoria, Reese Witherspoon, America Ferrera, Natalie Portman and more.
To donate to the Time’s Up Legal Defense Fund, which will provide subsidized legal support to women and men in all industries who have experienced sexual harassment, assault, or abuse in the workplace, visit its GoFundMe page.
