A non-compete clause is a legal agreement between an employer and an employee that restricts the employee from working for competitors or starting a similar business for a certain period after leaving the company. This clause aims to protect the employer's trade secrets, customer relationships, and overall business interests. These clauses vary in duration and geographic scope, depending on the industry and specific job role. While they can help businesses maintain a competitive edge, they may also limit an employee's job opportunities and career growth, leading to debates about their fairness and enforceability in different regions, such as California or Texas.
