The voluntary guidelines from the Producers Guild of America (PGA) recommend that all productions provide in-person anti-sexual harassment training for all cast and crew before the start of each season.

They also urge producers to conduct meetings and casting sessions in a “professional, safe and comfortable” environment, among other steps.

“As producers, we provide key leadership in creating and sustaining work environments built on mutual respect, so it is our obligation to change our culture and eradicate this abuse,” PGA Co-Presidents Gary Lucchesi and Lori McCreary said in a statement.

The guidelines are initial recommendations from a task force the PGA created in October after allegations of misconduct against entertainment industry figures including producer Harvey Weinstein, who has been accused by more than 70 women of sexual misconduct, including rape.

Many of the accusations against Weinstein stemmed from actresses who said they were sent to meetings with him alone in hotel rooms. Weinstein has denied having non-consensual sex with anyone.

The PGA expelled Weinstein from the group in October.

The new guidelines are especially important for independent productions that are not being done at a movie or TV studio with a human resources department, McCreary said in an interview.

Lucchesi said the steps, which were unanimously ratified by the PGA’s board of directors, are meant to serve as “best practices” for the PGA’s 8,200 members.

“It’s really about setting the right tone and having the proper behavior,” he said. “You don’t want people to be insensitive anymore.”

The recommendations also offer advice to victims of harassment, starting with going to authorities if they believe a crime was committed, and taking notes shortly after an incident.
