The plaintiff also contends that, unlike the Workers’ Compensation Act, which imposes liability on the employer regardless of fault for injuries sustained during employment, § 31-290a applies only to the intentional act of an employer in discharging an employee for a reason prohibited by law. We are not concerned with the possible merit of that argument in an action at law pursuant to § 31-290a (b), in which the statute provides for an award of “punitive damages” and “any other damages caused by such discrimination or discharge” in addition to reinstatement of the job, back wages, reestablishment of employee benefits and reasonable attorney’s fees. The plaintiff elected the forum provided by the commissioner for adjudication of his claim. In a proceeding before the commissioner under § 31-290a (b), there is no provision for “punitive damages” or “any other damages caused by” a retaliatory discharge. The only monetary awards that the commissioner was authorized to make were back wages and reasonable attorney’s fees.
