Recent verdicts by the Supreme Court have consequences for employers liability. Employers were already hold liable for accidents as a result of unsafe working places. Since a few years employers are also hold liable for accidents of employers they can not affect (directly). Verdicts are based on the fact that the employer do not have sufficient insurance to financially protect the employee (like an accident insurance).
Responsibility for accidents moves more and more towards employers. Liability insurers respond to this sense of movement by extending cover on the liability policy. Some liability insurers even cover accidents in case the employer is not (held) liable at all, just to financially protect the employee (secondary benefits).
