In King County (Amalgamated Transit Union, Local 587), PERC held that ATU Local 587 committed a ULP when it submitted a permissive subject of bargaining to interest arbitration. Examiner De La Rosa found that King County’s decision to move the Millwrights from the Vehicle Maintenance Section to the Power & Facilities Section was a managerial prerogative and therefore a permissive subject of bargaining.
