Contested return of the Mucem president in Marseille

On November 1, 2026, Pierre-Olivier Costa announces he is resuming his duties as president of the Mucem in Marseille after four months of suspension, against a backdrop of union tensions and investigations. The following day, museum staff launch an open-ended strike to protest his return, in a context of accusations of toxic management and harassment, which he denies. On November 7, the city of Marseille suspends its participation on the Mucem's board of directors. On November 11, an investigation looks back at the accusations of sexual and moral harassment targeting the president, who was removed then reinstated at the head of the museum, and at the anger of staff.
