Labor organizing group pushes for Senate support.

A group of Democratic senators, led by Sen. Sherrod Brown, introduced a resolution to allow Senate staff to unionize and collectively bargain. The move comes more than a year after the House passed a similar resolution. However, Democrats would need to find nearly a dozen Republican senators in favor to overcome the 60-vote threshold to break a filibuster. Currently, only Sen. Ed Markey's staffers have unionized, but the Senate hasn't passed its own resolution to authorize unionizing, leaving organizers unprotected by federal labor laws.
