"The bill that would cover the rest of workers is the Paycheck Fairness Act. The law would both strengthen penalties to employers who retaliate against workers for discussing pay and require employers to provide a justification for wage differentials."

I'm cool with the first part. Information makes the free market better. The second part is problematic and will just add paperwork with about as much hope of being honest as the justification body shops use to get H1Bs instead of local workers.
