SAN ANTONIO - The National Air Traffic Control Union sued the federal government over the shutdown.
Today, hundreds of thousands of workers saw nothing but zero's on their paychecks.
They can't just walk off the job, air traffic controllers are considered essential and required to work during a government shutdown.
Here in San Antonio, there are more than 50 air traffic controllers working without pay right now.
They are hoping the shutdown ends quickly so they can get paid.
Travis Uhlhorn still can't believe it.
"I got paid one cent," Uhlhorn said.
and it's no typo.
"That's all we got," Uhlhorn said.
Uhlhorn represents the union of 51 air traffic controllers here in San Antonio.
All of them working without pay.
"We are still coming to work," Uhlhorn said.
Ensuring thousands of flights go smoothly.
"70 thousand flights a day, and we all make sure they go by safe," Uhlhorn said.
The government shutdown to blame.
Air traffic controllers continue to keep the sky's safe without money to pay their bills.
"It's not political to us, we are not playing the blame game, we just want to get paid," Uhlhorn said.
Air traffic controllers will get the money they missed after the government re-opens.
