What should be done if an employee is injured on the job?

In the event of an employee injury on the job, providing first aid and notifying a supervisor is the appropriate course of action. This choice is correct because it emphasizes the importance of immediate care and proper reporting protocols when dealing with workplace injuries.

First aid may be necessary to stabilize the employee's condition, prevent further harm, and alleviate pain. Administering first aid shows commitment to the employee's health and safety. It is also vital to notify a supervisor quickly; they can ensure that the proper procedures are followed, including documenting the incident, determining if further medical assistance is required, and assessing any potential hazards that led to the injury to prevent future occurrences.

Addressing the injury promptly and appropriately is also in line with workplace safety standards and legal requirements. This approach helps to create a safe work environment and establishes a culture of care and responsiveness among employees and management.

The other options do not prioritize the employee's well-being or adhere to safety protocols, making them less appropriate in a professional setting.
