In addition to the group of contractors and developers, local officials also are pushing for the Teamsters and the concrete companies to return to the negotiating table, citing a threat of more than 15,000 layoffs across several industries. Those at risk of being laid off include not just the 300-plus striking workers, but related tradespeople from industries including masonry, structural steel, roofing and more who cannot work because of the strike’s impact on active projects, according to the statement.
