Not strictly required, but California employers with five or more employees must provide sexual harassment prevention training, and a handbook is the standard way to document that alongside other required policies. It also protects you by putting your rules and expectations clearly in writing.

No, non-compete agreements are generally void in California, with only narrow exceptions such as the sale of a business. As of 2024, employers were also required to notify affected employees that any old non-competes no longer apply, and employees can now sue over them.

In most cases you can end employment without giving a reason, since California is an at-will state. The key is getting the details right: a terminated employee’s final wages are generally due immediately, and you can never fire someone for an illegal reason like discrimination or retaliation.

Take it seriously, document everything, and investigate promptly and fairly. Retaliating against an employee for filing a complaint is illegal and creates serious legal exposure.

It means either side can end the working relationship at almost any time, for almost any reason, without notice. The main limits are illegal reasons, an employer can’t use at-will status as cover for discrimination, retaliation, or another unlawful firing.
