Federal workers gathered Wednesday at the Hart Senate Office Building to protest the ongoing government shutdown, which has left hundreds of thousands of them without pay.

The workers held 33 minutes of silent protest, or one minute for every day the shutdown has lasted. Protesters shook their fists during the protest and chanted, “No more food banks. We need paychecks.”

They also held paper plates with messages written on them, such as “open the government” and “federal workers are going hungry.” The plates were reportedly meant to symbolize that some workers can’t feed their families without pay.
