You might think in 2013, employers know better than to threaten workers for attempting to unionize, but according to a recent federal complaint issued by the National Labor Relations Board, they haven’t. At least not Creative Food Group BWI. The BWI airport concessionaire has allegedly interrogated and threatened employees over their union activity. And now the feds are going to prosecute.

One bartender at Sam Adams Brewhouse was allegedly issued a written warning and had his hours cut back after participating in a “rally for employees rights.” Workers at Silver Diner also allege that they have been intimidated and threatened for their desire to unionize.

Well, if nothing else, the alleged anti-union actions of the AirMall-contracted concessionaires make a great case for the unionizing effort that hundreds of BWI food and retail workers have been attempting.
