Which of the following expenses must an insurer cover according to Part One of the Workers Compensation and Employers Liability Insurance Policy?

The correct choice indicates that an insurer must cover medical payments for diseases claimed after retirement according to Part One of the Workers Compensation and Employers Liability Insurance Policy. This part of the policy is designed to provide comprehensive coverage for employees who incur work-related injuries or illnesses, including medical expenses.

In the context of workers' compensation, employees may develop illnesses related to their job, sometimes manifesting after retirement. Coverage for medical payments is crucial because it ensures that former employees receive necessary medical treatment for occupational diseases, even if symptoms emerge long after they have left the workplace.

By including such coverage, the policy supports the principle that workers should not suffer financially due to health issues that arise as a consequence of their employment, aligning with the broader goal of workers' compensation systems to provide protection and support for employees.

Understanding this aspect of the policy allows for greater appreciation of the protections offered under workers' compensation laws, enhancing the duties of insurers to provide appropriate benefits to entitled employees regardless of their employment status.
