Deborah Dugan, the embattled president and chief executive of the Recording Academy, was fired by the group’s board on Monday following weeks of internal turmoil between the organization that runs the Grammy Awards and its new leader.

The academy announced Ms. Dugan’s removal in a letter from its executive committee, sent to the organization’s members. “We placed our trust in her and believed she would effectively lead the organization,” the committee wrote in the letter. “Unfortunately, that is not what happened.”

Ms. Dugan was first removed from her position in January, when the academy placed her on administrative leave five months after she joined the organization and 10 days before the Grammy Awards.

At the time, the academy attributed its decision to a “formal allegation of misconduct” against Ms. Dugan. But in a complaint filed with the Equal Employment Opportunity Commission, Ms. Dugan said her removal was retaliation for speaking up against misconduct within the organization, including sexual harassment, corrupt voting procedures and conflicts of interest among board members. She also said she was harassed by Joel Katz, a powerful industry lawyer with deep ties to the academy. He has denied the allegations.
