Employee disputes are rarely successfully sued on for tort causes of action as you propose. You don't have the kind of claim against co-wprkers that will cause any attorney to take the matter on contingency, and you cannot afford to bring such a lawsuit by funding it out of your own pocket. It sounds like a misunderstanding and hopefully your employer will be able to resolve it peacefully. In any event, you can't sue someone for causing you stress unless they were under a legal obligation or duty not to cause you stress. That is not ordinarily the case with respect to co-workers. Further, "it did not happen as they say it did" strongly suggests that something happened, that the co-wprkers are not making this up out of whole cloth maliciously, and that means there is not good grounds for any defamation action. There is no meaningful legal remedy for the unpleasantness of all this. Make it your objective to hold onto your job and to simply get through and past this matter.
My responses to questions on Avvo are never intended as legal advice and must not be relied upon as legal advice. I give legal advice only in the course of an attorney-client relationship. Exchange of information through Avvo's Questions forum does not establish an attorney-client relationship with me. That relationship is established only by individual consultation and execution of a written agreement for legal services.
