" The two largest rail unions, the Brotherhood of Locomotive Engineers and Trainmen and the Sheet Metal, Air, Rail and Transportation union, which represents conductors,
are holding their own ratification votes, the results of which are due November 21.
If one or both of those unions reject the deals, they would be prepared to strike December 9."
"If one or both of those contracts are voted down, the BMWED said it is ready to further push its strike date back to December 9."
