The Heritage Foundation has the details on how the Democrats have decided unionization trumps objective security concerns. Those security concerns could legitimately be hampered by unionization.
Last night, on a purely partisan 47–51 vote, the Senate rejected an amendment that would have stopped government unions from organizing Transportation Security Administration (TSA) employees. The vote was made possible by an announcement two Fridays ago by President Barack Obama political appointee and TSA Administrator John Pistole. Pistole rejected TSA’s original policy that collective bargaining’s inherently adversarial process would impair TSA’s ability to protect American air travelers. Pistole’s decision, coupled with Democratic control of the Senate, will net the labor movement—a majority of whom already work for the government—45,000 new members and $18 million a year in dues that are ultimately paid for by you, the taxpayer.
