The House Education and the Workforce Committee has scheduled a Wednesday hearing on three Republican bills that would represent some of the most far-reaching changes to federal labor law in decades. The legislation would mainly change the rules for workplace organizing elections, setting higher bars for unions to win.

Republican members of the committee argue the bills would balance the elections by ensuring that unions prevail only when they have definite majority support from workers. Democrats counter that the bills are intended to do little more than hobble unions’ chances of winning.
