Which of the following could be a result of workers' compensation insurance?

Workers' compensation insurance is designed primarily to provide financial support to employees who suffer work-related injuries or illnesses. The key characteristic of this system is that it offers medical care and wage replacement benefits to employees, typically regardless of who is at fault for the injury. This means that employees can receive immediate benefits without having to prove negligence on the part of the employer, thus ensuring that workers receive necessary support and care during their recovery.

This system facilitates a no-fault compensation model, which simplifies and streamlines the process for employees, allowing them quick access to benefits while also protecting employers from lawsuits related to on-the-job injuries. The nature of these benefits—covering medical expenses and providing income replacement during recovery—aligns perfectly with the aims of workers' compensation.

In contrast, the other options present scenarios that are not consistent with the standard principles of workers' compensation. Employees suing their employers for damages typically occurs outside of this system when negligence or intentional harm can be proven. Employers holding absolute liability for all injuries and denying all claims after investigation are scenarios that do not conform to the framework of workers' compensation, as the system is designed to offer a more balanced approach to workplace injuries without placing undue burden on employers or employees.
