Allegations of mistreatment
Several days after the release of Sausage Party, allegations of poor treatment of Nitrogen Studios employees surfaced in the comments section of an interview with Tiernan and co-director Conrad Vernon, featured on the website Cartoon Brew. Various anonymous comments, from individuals purporting to be animators who worked on the film in question, made claims including that Nitrogen forced them to work overtime for free and that some employees were threatened with termination. One individual stated that Tiernan had developed a reputation for "disturbing behaviour and abusive management style". Publications such as the Washington Post, the Los Angeles Times, Dorkly, and Film later picked up the story.
