Abruzzo, immediately prior to her appointment by President Biden as NLRB GC, “served as CWA’s ‘special counsel for strategic initiatives’” and “acted as that union’s ‘point person on National Labor Relations Board issues at’” the CWA’s headquarters in Washington, DC. Because Brown’s case concerns CWA’s international policy forcing workers like Brown who abstain from formal union membership to write the national union if they want to exercise their right to not pay for the union’s political activities, Abruzzo’s involvement in the case would constitute a serious conflict of interest, the letter argues.
