It would grant workers three unpaid sick days as long as the employers were provided with at least 30 days' notice before the time was taken.
They are asking for seven additional days of paid sick leave — a demand the House moved to grant Wednesday.
John Thune, R-S.D., predicted Thursday the Senate will vote on a bill to avert a rail strike.
That high bar to clear made it significantly more difficult for the chamber to pass the seven days of sick leave measure, which had limited support among Republicans — to the frustration of Sen."I'm going to vote yes on the sick leave, because that's what the workers actually want, and I'm going to vote no on the underlying bill because I don't support it, and the workers don't support it," Hawley said.But on the underlying bill to avoid the shutdown, even Democrats demanding better treatment for rail workers were reluctant say they would vote against it — even without the additional sick leave.
