Small Business Compliance Cheat Sheet – Federal Employment Laws by Employer Size

An employer’s size, meaning the number of employees, is a key factor in determining which federal laws—including employment, health care, safety, privacy and financial laws—the organization must comply with. Determining an employer’s size can vary depending on the types of employees, where the employees are located and a law’s specific requirements. It’s vital for small businesses to be aware of the sized-based federal laws that may apply to their organizations to ensure they’re complying with all applicable laws and regulations. This is especially important for employers with fluctuating workforce numbers or who are considering hiring additional employees. Knowing which federal employment laws apply can enable small businesses to remain compliant, improve organizational efficiency, enhance employee morale and well being, and set up for long-term success.

This cheat sheet provides a broad overview of key sized-based federal employment laws. If small businesses have questions regarding which federal, state and local governments may apply to their organizations or how to best navigate those laws, they should reach out to their local legal counsel.
