Oklahoma Notice to Injured Workers is a form issued by the Oklahoma Workers' Compensation Commission that informs injured workers of their rights under state law. This notice is issued to employees who have sustained an on-the-job injury that is covered under Oklahoma’s workers’ compensation system. The notice outlines the employee’s rights to compensation for medical expenses, lost wages, and other benefits. It also explains the process for filing a claim and seeking a hearing if a dispute arises. There are two types of Oklahoma Notice to Injured Workers: the Form 3 and the Form 4. The Form 3 is issued when the employer has accepted liability for the injury, while the Form 4 is issued when the employer has denied liability.
