A stipulation for actors part of the SAG-AFTRA strike is not to promote any struck material on social media. That means even though “Chicago Fire” isn’t airing new episodes at the moment, actors could still get in trouble if they posted anything about their work, including behind-the-scenes pictures. Some actors have already gotten in hot water for breaking the rule, like Selena Gomez, who published (then deleted) an Instagram post about the new season of “Only Murders in the Building.” Actors can post about other topics or show what else they’re up to in life, but it’s feasible some don’t want to risk anything and are laying low just to be safe.
On the other hand, it could be entirely a coincidence that several “Chicago Fire” actors have taken a break from Instagram. Maybe they’re enjoying this reprieve from filming and don’t want to be bothered with posting on social media all the time. One topic 100% allowed via SAG-AFTRA rules is posting on social media in solidarity with the strikes. Many members of the “One Chicago” family, including Jesse Lee Soffer and Tracy Spiridakos of “Chicago P.D.,” were spotted on the picket lines not too long ago.
Again, there may be no real reasoning behind the lack of Instagram posts from “Chicago Fire” actors in recent months. But fans wanting updates on Season 12 will have to look elsewhere.
