14. Eduardo owns a licensed company that supplies janitorial and messengerial aides to various businesses, including Gloria Restaurant (GR). The tools and supplies used by the janitors and messengers are supplied by the clients who also train the workers and monitor their performance. Their minimum wages are paid by the clients through Eduardo. After two years of working in GR, the janitors and messengers joined the union there to receive the same benefits as the directly hired employees of GR. Can the janitors and messengers legally join the union? Discuss.
