The House passed a resolution Tuesday night allowing congressional staff to unionize, approving the measure by a party-line vote of 217 to 202.
The move, sponsored by Democratic Congressman Andy Levin from Michigan, allows House staff members to form unions and collectively bargain, although it limits their ability to negotiate on wages and benefits. It only applies to staffers in the House, not the Senate.
"The Congress has long been strengthened by the skill, dedication and patriotism of our hard-working staffers, who enable us to fulfill our legislative and constituent responsibilities," House Speaker Nancy Pelosi said in a statement Tuesday night. "The Democratic House is committed to honoring their service, while ensuring the Congress is well-positioned to compete for outstanding and diverse staff."
