The US Department of Labor is reassessing a decade-old rule that extended pay protections to home health aides, a move that has the potential to impact the wages of millions of US workers.

In a footnote in a court filing last month, the agency said it “intends to reconsider” regulations issued in 2013 under President Barack Obama, which expanded the scope of minimum wage and overtime rules to cover so-called “direct care” workers such as home health aides and certified nursing assistants.
