In a major win for employers, the U.S. Court of Appeals for the Fifth Circuit has shot down a National Labor Relations Board ruling forcing the Convergys Corp. to stop requiring its job applicants to sign class action waivers that prevent them from suing the company.

The recent 2-1 decision in Convergys v. NLRB rejects the board’s finding that the Ohio-based customer management company violated worker rights to self-organize under the National Labor Relations Act by requiring potential employees to sign class action waivers.
