a screenshot from the Hollywood Reporter piece, which reads: " Now, nearly half a year later, the union has reached a settlement with Condé Nast over the discipline, The Hollywood Reporter has learned. As part of the deal, the status of three of the four workers was changed from fired to being allowed to resign as active employees.
