What action is an employer prohibited from taking if an employee exercises their OSHA rights?

Employers are prohibited from discriminating against an employee who exercises their rights under the Occupational Safety and Health Administration (OSHA) regulations. This means that if an employee reports unsafe working conditions, requests a safety inspection, or engages in any activity protected by OSHA, an employer cannot treat them unfairly or take adverse actions based on that participation.

Discrimination can occur in various forms, including demotion, harassment, or any punitive measures that can create a hostile work environment for the employee who has asserted their rights. This protection is crucial for ensuring that workers can safely advocate for safer workplace conditions without fear of retaliation, which encourages a culture of safety and accountability within the workplace.

The other options reflect actions that could be interpreted as discriminating against the employee, such as termination, restricting access to safety equipment, or disregarding complaints. However, the specific prohibition of discrimination encompasses a broad range of retaliatory behaviors, making it the most accurate answer in this context.
