In California, the poster that communicates wages, hours, and working conditions is the Industrial Welfare Commission (IWC) Wage Orders poster. These Wage Orders are the official rules for different industries and include essential details on minimum wages, overtime, meal and rest breaks, and other working conditions. Employers are required to display the appropriate Wage Order poster in a conspicuous place where employees can easily read it. The other posters mentioned aren’t the official notice that summarizes wages, hours, and working conditions, so the mandated poster is the IWC Orders, commonly referred to as Wage Orders.
