Hundreds of people who worked on the World Trade Center cleanup have filed a class-action lawsuit against Silverstein Properties, the leaseholder of the towers, and four construction companies who supervised the removal of debris. The lawsuit, made public today, alleges that the workers did not have access to protective gear. The suit includes about 800 plaintiffs and was filed the last day before the federal three-year statute of limitations expired for lawsuits related to the terrorist attack. Some of the plaintiffs who do not currently suffer any symptoms from working on the site joined the lawsuit fearing risks that could develop later. Just last week, the CDC released a study which indicated many workers at the site suffered from respiratory problems long after the cleanup concluded. Read the CDC report here. AP has more.
