Air traffic controllers who duck unpaid work during the gov't shutdown could be fired, Duffy warns

Even though the U.S. has a stark shortage of air traffic controllers, ones who call in sick instead of working without a paycheck during the risk being fired, the U.S. transportation secretary warned.

Transportation Secretary Sean Duffy said this week that he understands the controllers' frustrations and worries. But during an appearance Thursday on Fox Business, he said that by calling in sick they are causing major disruptions to air traffic, and it won't be tolerated.
