In the case of Brennan, Secretary of Labor v. Arnheim & Neely, Inc., et al., 1972, the U.S. Supreme Court ruled in favor of the Secretary of Labor who had filed a lawsuit against real estate firm Arnheim & Neely for alleged violations under the Fair Labor Standards Act (FLSA). The company argued that its employees were exempt from overtime pay requirements because they were administrative or executive staff. However, upon review and application of FLSA standards to determine whether an employee is considered "administrative" or "executive", it was found that these employees did not meet those criteria as their primary duties did not involve management policies nor require specialized educational training. Therefore, they should have been eligible for overtime pay according to federal law. The court's decision clarified how job duties are evaluated under FLSA exemptions and reinforced employers' obligations to comply with federal wage laws regardless of job titles given to workers.

In the dissenting opinion for Brennan, Secretary of Labor v. Arnheim & Neely, Inc., et al., Justice William O. Douglas argued that the majority's decision to uphold a lower court ruling exempting real estate brokers and salesmen from overtime pay requirements under the Fair Labor Standards Act was incorrect. He contended that Congress intended for these workers to be covered by this law when it expanded its scope in 1966 to include employees of schools and hospitals among others. According to him, there is no evidence suggesting that Congress meant to exclude real estate professionals specifically from these protections while including other similarly situated workers. Furthermore, he pointed out inconsistencies in how different types of businesses were treated under this law as a result of this ruling which could lead to confusion and unfairness.
