Final answer:
An employee should file a grievance with the human resources department if they feel unjustly treated, especially regarding safety concerns or non-compliance with workplace standards like those from OSHA.
Step-by-step explanation:
An employee who feels unjustly treated should file a grievance with the human resources department. An employee grievance is a formal complaint made by an employee towards an employer within the framework of a company's grievance procedure. This process is in place to foster a safe and fair work environment. In situations related to safety concerns or non-compliance with standards, such as those set by the Occupational Safety and Health Administration (OSHA), employees have the right to file a complaint without the fear of retaliation. Filing a complaint like this comes with protections under the Occupational Safety and Health Act, where any adverse actions taken by the employer against the employee for utilizing these rights can be deemed illegal.
