President Joe Biden announced sweeping federal vaccine requirements that are expected to affect as many as 100 million American, including many in West Virginia.

The expansive rules mandate that all employers with more than 100 workers require them to be vaccinated or test for the virus weekly, affecting about 80 million Americans. And the roughly 17 million workers at health facilities that receive federal Medicare or Medicaid also will have to be fully vaccinated.

"So tonight, I'm announcing that the Department of Labor is developing an emergency rule to require all employers with 100 or more employees, that together employ over 60 million workers, to ensure their workforces are fully vaccinated or show a negative test at least once a week,” Biden said.

The president also signed an executive order requiring vaccinations for employees of the executive branch and contractors who do business with the federal government with no option to test out.

The moves cover several million more workers like those at the national park in Fayette County. It also follows an alarming rise in coronavirus cases and a stagnating pace of vaccine shots.

The head of the largest federal union representing government employees -- including some in the Park Service -- said these changes have to be negotiated and the president can't just arbitrarily impose them.

American Federation of Government Employees National President Everett Kelley said while he favors vaccinations, “changes like this should be negotiated with our bargaining units where appropriate.”

Put simply, workers deserve a voice in their working conditions. Park visitors were split on the shot requirements.

“I think that any employee needs to abide by the policies of their employer,” Brant Gurganus, of Indiana, said.

“I think that every American should get to make their own decision – federal employee or not,” Sherry Taylor, of North Carolina, said.
