At the beginning of 2018, more than 300 women in the entertainment industry launched a new effort aimed at addressing the systemic problem of sexual discrimination and inequality in workplaces across industries. Called Time's Up, the initiative began in the wake of the #MeToo movement, which gained traction late last year following sexual misconduct allegations from multiple women against Hollywood executive Harvey Weinstein.

Now, women in the advertising industry are taking their own stand with Time's Up/Advertising. The movement was born of conversations started in late January among a small group of women that quickly grew from 14 to 200 by the time of its official launch in March, according to the group's website. The site features a Letter of Solidarity signed by female executives within the industry, from agency presidents and CEOs to creative directors and CMOs.

"As women in senior leadership positions in advertising, we've agreed that we have the power to change this business we love until it looks more like the industry we want to lead," the letter reads. "As leaders, it's on us to foster a workplace where people are challenged but still respected."
