TSA Screeners Choose Their Union CheapOair Staff June 24, 2011 general The airport screeners of the Transportation Security Administration have chosen the American Federation of Government Employees as their official union. The AFGE is under the AFL-CIO and will now represent over 40,000 workers. AFGE beat out the National Treasury Employees Union just barely in a runoff vote. Screeners now have limited collective bargaining rights, with pay and security issues being the two exceptions. Workers are also banned from striking. TSA screeners made plans to join a union months ago after the Obama administration granted they could do so. A first vote between the AFGE and NTEU was held in April, but neither achieved a decisive majority.
