On a teleconference today at 3:45 EST, the administrator for the Transportation Security Administration (TSA), John Pistole, will announce a framework allowing Transportation Security Officers (TSOs) to vote on union representation.

According to a press release from TSA, the framework is “for the purposes of engaging in limited, clearly defined collective bargaining at the national level only on non-security employment issues. If a union is chosen, each security officer will retain the right to choose whether or not to join the union.”
