New York, NY – December 14, 2011 – (RealEstateRama) — Thousands of New York City office cleaners and other commercial building workers marched and rallied through the streets of Midtown Manhattan today during rush hour to demand a fair contract from the Realty Advisory Board, an industry association representing most building owners. With only two weeks left until a possible citywide strike, 32BJ SEIU and the RAB remain far apart on any new agreement.
