In Muscat v. Minacs Group USA, Inc., the plaintiff argued that he was entitled to be paid overtime. He was in charge of a training group of 25-30 people at a time. He was allowed some discretion in how fast training should proceed, and in motivating and disciplining the group's individuals. He also made recommendations regarding hiring and firing.
The Court held that because he was directly engaged in personnel management, he was exercising "discretion and independent judgment with respect to matters of significance," and therefore he was not subject to overtime under the FLSA.
