North Carolina is an employment-at-will state which means you can be fired (or anything short of firing) for any reason and there is no liability for the employer unless there is an unlawful motive for the action taken against you. There are generally only two forms of unlawful motives: unlawful discrimination or unlawful retaliation. Discrimination in employment is unlawful if it is due to race, color, sex, national origin, religion, disability or age 40 or older. Retaliation in employment is unlawful if you engaged in one of a handful of "legally protected" activities and were fired for engaging in that activity.   If either of these was the motive for what happened to you, then you may have a legal claim. However, fact that these things were done to you with "no good reason" shows that it was an unfair situation. It does not show that what happened was unlawful. Additionally, there is no legal claim for hostile enviornment (a form of unlawful harassment) unless it is directed to you on the basis of unlawful discrimination as described above.
