As a result, California employers are required by law to have workers' compensation insurance, even if they have only one employee. And, if your employees get hurt or sick because of work, you are required to pay for workers' compensation benefits.
Once a completed Workers' Compensation Claim Form(DWC 1) & Notice of Potential Eligibility (e3301) has been received from the employee, authorization for medical treatment must be given within one working day. Employers are responsible for paying up to $10,000 in medical treatment until a claim is denied.
