negotiations and is just a reminder of what was and was not included in this deal. there was an agreement to include a 23% -- 24% raise by 2023 and a cap on health care premiums, but what was not included was 15 days of paid sick leave. that is something that unions wanted and that is why four unions rejected it. they have until december 9th to ratify this agreement. now it's up to congress. this is something biden is putting on congress. it is a political last resort for him. he did not want to force this deal on unions and workers since he has been a pro-labor champion, but he wanted to avoid what many experts are saying would be an economic catastrophe, especially right before the holidays, a rail shutdown or strike would disrupt supply chains, computer rail and could cost the economy a billion dollars within first week. it's something that all sides are looking to avoid right now and capitol hill will be the next move. >> melanie zazona, thank you so
