Most employees in this country work at will, which means they can quit at any time and can be fired at any time, with or without notice, and with or without cause. (For more information, see Nolo's article Employment At Will.) However, even an at-will employee can't be fired for a reason that's illegal. For example, employees cannot be fired for reasons that are discriminatory, intended to punish the employee for whistleblowing, or in violation of employee protection laws, such as the National Labor Relations Act or OSHA.
Below, you'll find information on common grounds for wrongful termination claims. You'll also find information on finding a lawyer, something you will likely need to do if you are considering taking legal action against your employer. A lawyer can evaluate your claims, let you know your chances of success, help you negotiate with your employer, and much more, even before you file any papers in court. Most legal claims, including employment claims, settle well before anyone sees the inside of a courtroom. A good attorney can help you make sure you get the best possible settlement under the circumstances.
