U.S. House and Senate Democrats have reintroduced the PRO ACT, a sweeping pro-union bill that would wipe out right-to-work labor laws in 27 states.

Democrats argue the PRO Act will create safer workplaces and increase employee benefits by expanding union organizing. Those opposed to it argue it will force small businesses to close, cost an untold number of jobs and worsen the economy, and “impose a laundry list of other union boss power grabs.”
