Wrongful termination is a legal issue. I am not a lawyer (IANAL).
I read questions on Internet forums every day. Often these questions are about handling termination situations. A Company fires a person. The person goes on the Internet to get advice on suing the company that fired them.
The people responding with advice don’t always give their qualifications. Some state that they have so many years of experience in management. Others state that they have so many years of experience in human resources. These people are just responding with their feelings or opinions or examples. But if they are not an attorney, I suggest that you not use input from forums to make decisions about claims of wrongful termination.
However, pursuing a settlement in the courts for wrongful termination is a legal matter and is often a complex legal matter. You may want to research the costs and commitments of working with an attorney. This page on the CONSUMER PROTECTION DEPARTMENT OF JUSTICE (https://www.justice.gov/jm/jm-4-8000-consumer-protection) may help you with your research.
Additionally, before you threaten to sue your employer, I recommend that you get legal advice from an attorney.
Legal Issues for Wrongful Termination
There is no single law for matters relating to termination. Employment laws vary from state to state. In some states, companies can require employees to agree not to go to work for a competitor. These contracts usually limit the agreement for a certain amount of time after leaving a company. Some states do not allow companies to impose non-compete restriction on employees. Before signing that type of agreement, research the legality of that agreement in terms of the contract and in terms of your location.
In conclusion, I do not recommend that you act solely on the advice from an Internet forum. At the same time, you can learn a great deal about the best thing to do when you believe that your employer has violated your rights. You have rights. Your employer has rights. Act intelligently in respecting the rights of your employers while protecting your rights of employment.
