The NLRA’s definition of “employer” includes any employer that affects interstate commerce. “Affecting interstate commerce” is traditionally a very broad term, and the vast majority of employers fall within this definition. The NLRA excludes several groups of employers from its scope, including the following:

• The Federal Government
• Any wholly owned government corporation or federal reserve bank
• Any state government or political division of a state
• Employers subject to the Railway Labor Act
• Labor organizations, with some exceptions
