Washington Minimum Wage Card for Workers is a document issued by the Washington State Department of Labor and Industries (L&I) that provides detailed information on the minimum wage rate in the state. The card outlines the current minimum wage rate, the date it went into effect, and any applicable exemptions. The card also includes instructions on how to report any violations of the minimum wage law. There are two types of Washington Minimum Wage Cards for Workers: one for employees working in Washington State, and one for employees working in any of the other states that have adopted Washington's minimum wage law. Employees must carry the card with them while working and present it if asked by their employer. The card serves as a reminder of the current minimum wage rate and the employer's obligation to pay it.
