What we know:While benefit checks and mail delivery will continue, hundreds of thousands of federal workers across the country are being furloughed. At Hartsfield-Jackson International Airport, where roughly 1,200 Transportation Security Administration employees work, the mood was described as "somber." TSA union spokesperson Aaron Barker said agents reported for duty Wednesday knowing they would not be paid until the shutdown ends. What they're saying:"The average American citizen is living paycheck to paycheck," Barker said. Despite financial concerns, Barker said TSA employees are still reporting to work and continuing their duties without disruption.
