- Congress intervened as the threat of a strike loomed but did not pass the paid sick leave provisions workers sought.- The workers and companies had until Dec. 9 to reach an agreement before they vowed to strike, which the industry estimated would cost the U.S. economy $2 billion per day."But it was the right thing to do at the moment to save jobs, to protect millions of working families from harm and disruption and to keep the supply chain stable around the holidays."Biden said Thursday he supports unions as much as ever, but as president of the United States, rather than a single senator from Delaware, it was his job to look out for all Americans.He said has long been a proponent of paid sick leave, and will still work to make it a right for all workers, not just rail workers."
