Decisions and Opinions of the Illinois State Labor Relations Board

Justice Birkett delivered the judgment of the court. Justices Bowman and Schostok concurred in the judgment.The evidence presented at a hearing before the Illinois Labor Relations Board, State Panel, was sufficient to prove that the sergeants employed by the Oak Brook Police Department had supervisory authority in the following areas: (1) direct; (2) discipline; (3) reward, (4) promote; and (5) adjust grievances. Therefore, the Board clearly erred in ruling that the sergeants were not supervisors within the meaning of the Illinois Public Labor Relations Act (5 ILCS 315/3(r) (West 2010)) and subsequently certifying the Metropolitan Alliance of Police, Oak Brook Sergeants No. 54 as the exclusive representative of the Oak Brook Village's sergeants.
