Millions of Americans who voted for Donald Trump are expected to lose overtime pay rights soon after he is sworn in as president.

Tom Bonier, CEO of the polling firm Targetsmart, pointed out on Monday that “almost 20,000,000 Trump voters would lose time and a half overtime” under a Republican plan to reverse regulations put in place by President Barack Obama.

According to Politico, House Republicans are already plotting the most efficient way to dismantle Obama-era regulations. An overtime rule requiring companies to pay time-and-a-half to workers who make less than $47,000 a year is expected to be one of the first reversals.

“We have heard over the past year that it would have truly dramatically bad effects, not just on employers but on employees across the country,” Rep. Bradley Byrne (R-AL) told Politico. “I can give you the names of a ton of private-sector businesses who will either have to eat that cost or pass that cost on to their customers.”

Exit polls taken during the Nov. 8 election showed that 41 percent of Trump’s 61 million votes were cast by people who make less than $50,000 a year.
