By law, all US employees have a right file a complaint against their employer without the fear of retaliation. Anytime a worker has a strong, valid belief that their employer is breaking a law, denying them safety in the workplace, or setting unreasonable work terms, the worker is encouraged to take action whether they're a union member or not. According to the US Constitution, even government employees may exercise free speech without fear of retaliatory action. "Whistleblowers" is a common term applied to those who report unlawful workplace activities. Whether they are right or wrong for filing a claim they are still protected under such laws and acts as the Sarbanes-Oxley Act of 2002. All employees have the right to stand up for themselves without the possibility of being harassed, threatened, suspended, demoted, or discriminated against by their supervisor.
