Due to the investigation into “The Flash” and “Supergirl” executive producer Andrew Kreisberg, Greg Berlanti and Sarah Schechter of Berlanti Productions have been meeting with the casts and crews of their series in recent days.

On Nov. 10, Variety reported that Kreisberg, an executive producer of “Supergirl,” “The Flash,” “DC’s Legends of Tomorrow” and “Arrow,” was suspended pending an investigation by Warner Bros. TV, in connection with alleged sexual harassment, inappropriate conduct and unwanted touching. That investigation is still ongoing. Kreisberg has denied the allegations.

On Monday, Tuesday and Wednesday, Berlanti and Schechter, who head up Berlanti Productions, which produces the shows, held meetings with the casts and crew of all of their series — both in Burbank as well as Vancouver, where many of the superhero shows are filmed. Those meetings, which were mandatory for employees in Burbank, are expected to continue Thursday and Friday.

At the meetings, staffers were encouraged to contact Warner Bros. HR if they had information relevant to Kreisberg’s case or to any other matter relating to safety, inappropriate behavior or harassment. Sources say Berlanti was “apologetic” that employees had not felt empowered to come forward. The purpose of the meetings is to reassure everyone that their jobs were secure, and give them an opportunity to air any grievances without fear of retribution.

“It seems like they’re committed to repairing the damage that’s been done, but in some ways, it feels like too little, too late,” says one source.

An annual visit by CW president Mark Pedowitz to the network’s Vancouver-based series was supposed to begin on Monday, but that visit was postponed for the moment, sources tell Variety.

While Kreisberg’s fate is ultimately up to Warner Bros. HR and the results of their investigation, two sources said there would be a “mass walkout” if Kreisberg ever returned to any of the superhero programs.

“Until action is taken, going to H.R. seems like a fool’s errand,” says one source. “I want to believe the process can work, but I’m just not sure it can. I have to see evidence of it first, in the form of him being gone permanently.”
