As the Trump administration ramps up its crackdown on immigration, undocumented workers in the construction industry claim raids and arrests have emboldened some contractors to cut pay and increase hours.

Rogelio, a tile setter, works for various contractors in the the Tucson, Arizona, region. He is undocumented, and did not provide his full name.

When Donald Trump returned to office in January, Rogelio said his employers cut their rates by 30% to 40%. Other laborers told him they had endured similar treatment.

“They decreased the pay by piece because they know most of the tile setters don’t have social security numbers, so they take advantage of that. We are in their hands,” Rogelio told the Guardian. “It’s more work, less pay. We have no choice right now.
