Recently, the U.S. District Court for the District of Arizona held in Castillo v. Spencer’s Air Conditioning & Appliance, Inc., 2024 WL 706939, that while the question of whether an entity is a joint employer under the Fair Labor Standards Act (FLSA) is a question of law, summary judgment was not appropriate because there were material disputed facts at issue in the analysis of the economic reality of an alleged joint employment relationship.
