Also, a lot of employees seem to think that all retaliation by an employer is illegal. But that too is not correct. What is illegal, generally speaking, is retaliation against an employee for (1) making job safety or other protected complaints to the government and (2) the employee exercising some legal right that he/she has, like making a complaint to management about illegal discrimination in the workplace (e.g. discrimination based on race, color, national origin, sex, religion, age, disability, etc).
