Upon request, employers must provide workers with which of the following?

Employers are required by law to provide workers with records of work-related injuries and illnesses upon request. This obligation is primarily established under the Occupational Safety and Health Administration (OSHA) regulations, which aim to ensure that employees have access to information regarding workplace safety and health. These records allow workers to be informed about potential risks and safety trends in their workplace, contributing to a healthier work environment.

Other options, while beneficial to the employees in various ways, do not carry the same legal requirement. Pay stubs may be provided upon request, but they are not mandatory in all jurisdictions for employers to proactively distribute. Training manuals can be essential for employee onboarding and ongoing education, but their provision is not dictated by regulation in the same way as injury and illness records. Vacation policies are typically outlined in employee handbooks or contracts, but employers are not legally bound to provide these upon request in a specific manner.

Therefore, the legal requirement for employers to provide records of work-related injuries and illnesses is the most critical aspect of health and safety protocols in the workplace, ensuring transparency and accountability in maintaining a safe working environment.
