The purpose of any business contract, including for employment, is to make the agreement and responsibilities between two or more parties explicit and legally binding. However, it doesn't guarantee the parties will fulfill their ends of the contract. When this happens, it's an actual breach of contract, and the harmed party can take legal action against the one who made the breach. The type of breach determines whether or not the affected party still has to perform its duties and maintain the contract. The two main types of actual breaches are minor and material.
Workplace discrimination is a very serious issue in the United States. The Equal Employment Opportunity Commission has rules set forth to help ensure that workplaces remain free of discrimination.
