Returning to your alma mater isn’t always rainbows and sunshine, especially when you’re the CEO and president of Warner Bros. Discovery. David Zaslav found that out the hard way while giving a commencement speech at Boston University in the midst of the Writers Guild of America strike. This reportedly led to jeers and chants of “pay your writers.”

Deadline reports there was an official WGA picket line outside of the graduation ceremony, but some students apparently vocalized their support for the strikers while Zaslav spoke. Late Night with Seth Meyers writer Mike Scollins shared a video on Twitter showing the Warner Bros. Discovery boss–who graduated from Boston’s law school in 1985–interrupted by chants of “pay your writers.” Zaslav never commented on the strike during his speech.
