KUSA - A dozen people who work in Denver's EPA office demonstrated Friday against the shutdown.
Many are calling this whole issue a "lockout" as opposed to a shutdown.
Some of the employees are filing for unemployment benefits and worried about how they will make mortgage payments if this shutdown continues much longer.
"I think we have about 500 people in our building that are not working," Local AFGE President Britta Copt said.
Although it may not be visible, the work is piling up behind the scenes.
"We get drinking water results in, and unfortunately, all the monitoring right now is going to an empty office," engineer Mindy Mohr said. "No one is looking at it to see if the water is safe in Wyoming or on tribal lands."
The office in Denver is a regional office for the EPA and monitors water, air, and hazardous waste pollution for Colorado and five other states.
