Kentucky is among a coalition of 21 states suing the U.S. Department of Labor over a new rule that would make more higher-earning workers eligible for overtime pay.
Nevada Attorney General Adam Laxalt filed the lawsuit in Texas Tuesday, urging the court to block implementation before the regulation takes effect on December 1.
The measure would shrink the so-called "white collar exemption" and more than double the salary threshold under which employers must pay overtime to their workers.
Laxalt said the rule would burden private and public sectors and represents inappropriate federal overreach.
Officials from the labor department didn't immediately respond to requests for comment.
