The charge, which was filed with the National Labor Relations Board (NLRB) by a former campaign employee on July 22, also alleges that the campaign violated a collective bargaining agreement with unionized workers by making staffers work additional days and failing to provide commensurate days off.

When the individual asked the campaign to abide by the terms of the collective bargaining agreement, management retaliated, the charge alleges.

“[Campaign management] retaliated against me when I organized the bargaining unit and sent an email requesting compliance with the [collective bargaining agreement],” the person wrote in the charge.
