On Wednesday, construction came to halt at 30 sites in New York City, including Hudson Yards, after cement workers went on strike. Crain’s reported, “At midnight this morning, a collective bargaining agreement ran out between the council of carpenters and a trade organization called the Cement League. The league is made up of contractors that erect the concrete skeletons for high-rise buildings and hire district council workers for part of that job under a collective contract.” As of Wednesday afternoon, the strike was ongoing.
