Operating Engineers Local 99 and its supporters will rally in front of the CIA this afternoon. Frustrated members authorized a strike after bargaining with AECOM stalled recently and the rally – which starts at 2:30pm at Langley Fork Park in McLean -- is intended to help them settle a fair contract and avoid a strike. “The workers at the site have received only one raise in five years and now AECOM is seeking huge concessions,” reports Local 99. Local 99 represents 3500 skilled men and women running HVAC systems, boilers, chillers and electrical systems in office buildings, hotels, government sites, universities and hospitals throughout the Washington metropolitan area.
