Nevada is a "Right to Work" State, which means that in Nevada there is not a strict obligation to be part of a Union in order for an Employer to hire you. Since you do not have the Union protection typically, you can be fired from your job for any reason, except for one of the following three:
If you are part of a Union, the Collective Bargaining Agreement that your Union negotiated with the Employer on your behalf protects you. This means that the agreement made between your Union and the Employer has a section that explains the process an Employer must go through in order to terminate a Union employee. In most cases, your Union will have a Grievance system, whereby you will be able to contact your Union representative and request that the Employer's disciplinary action be challenged. If you need more information on how your grievance process works, you should contact your Union representative or obtain a copy of your Collective Bargaining Agreement.
If you have an employment contract with your Employer then you are protected by whatever terms are in your contract. Typically, an employment contract is reserved for high level executives in companies, however if you do have an agreement with your employer you may want to look for a provision in that agreement which outlines your rights under termination. Some contracts may have language that protects you from termination or perhaps even give you a chance to address any issues regarding employer discipline. The best thing to do would be to hire a lawyer to look at your employment contract and advise you on whether you have any rights under that agreement.
Third, if you have been discriminated against based on one of your Title VII rights: age; disability; genetic information; national origin; pregnancy; race/color; religion; and/or sex, and were subsequently fired, then that is wrongful termination. In order for there to be wrongful termination based on discrimination you need to have been treated differently by a co-worker or supervisor. That different treatment was reported to management (or human resources) and that as a result you were retaliated against by management and fired.
Of course, if you truly feel that you were wrongfully terminated you should consult an attorney on your matter.
