The Sergeants Benevolent Association (SBA) is an American police union that represents the sergeants of the New York City Police Department (NYPD), while the department's nonsupervisory patrol officers are represented by the larger Police Benevolent Association. The SBA is characterized by the Associated Press as a partisan organization, and is known for perpetually criticizing the Mayor of New York City (especially recent mayor Bill de Blasio), unfavored police commissioners, and other politicians through an inflammatory Twitter account, press releases and other media statements.
