Business groups and unions expect the U.S. Senate to vote in the
next week or two on a joint resolution for congressional
disapproval that would block the National Labor Relations
Board’s union election rule. The rule would speed up union
elections and is opposed by business groups, which say that it
would restrict employers’ free speech rights and put a damper
on job growth. However, unions support the rule, indicating that
it would give workers a fair vote and minimize litigation. The
joint resolution has the backing of 45 Republicans, but it needs
a simple majority of 51 votes to pass.
