Some federal workers are sending a message to Washington letting them know they don't agree with the partial government shutdown.

The Associated Press said roughly 800,000 federal workers - more than half of them still on the job - are set to miss their first paycheck Friday under the stoppage that began Dec. 22.

Hartsfield-Jackson officials told 11Alive Thursday about 25 TSA agents protested around noon at the domestic terminal- north at the airport.

While furloughed federal workers have been given back pay in previous shutdowns, it's not guaranteed that will happen this time. Government contractors, who have been placed indefinitely on unpaid leave, don't get compensated for lost hours.

Most of the government workers received their last paycheck two weeks ago.
