The document discusses the evolving definition of 'joint employer' according to the NLRB, specifying that joint employers can share liability for unfair labor practices and must negotiate with unions representing employees of the other company. It outlines the current standard set by past cases which require 'direct and immediate' control over employment terms and conditions, while mentioning a proposed change that could broaden the definition of joint employers. The webinar presents potential implications for employers in light of upcoming NLRB changes and suggests strategies to manage risks associated with joint employer status.
