He has no case against you. He is trying to bully you.
In no way am I offering you legal advice, and in no way has my comment created an attorney-client relationship. You are not to rely upon my note above in any way, but insted need to sit down with counsel and share all relevant facts before receiving fully-informed legal advice. If you want to be completely sure of your rights, you must sit down with an experienced criminal defense attorney to be fully aware of your rights.
Nevada is an employment at will state, which means you can be hired or fired for any reason or no reason (as long as there's no discrimination or other unlawful behavior). Unless you have an employment contract, you are not required to give your employer notice that you are leaving. You also do not have to train your replacement.
Under Nevada law, if you quit your job, the employer must pay you on your next regular pay day or within 7 days, whichever is earlier. If this time period has lapsed, you can file a complaint against the employer with the Nevada Department of Business and Industry, Office of the Labor Commissioner. Good luck.
NV is an at will employment state and you can quit for whatever reason you want, even without any notice.
The information provided in this answer does not create an attorney-client relationship and is not considered to be legal advice. Mr. Leroi answers questions on Avvo because he strongly believes in public service from his years as a judge, magistrate, and prosecutor. If you need to ask any follow up questions because my answer did not fully address your question, feel free to call Chris or post an additional question. Thank you.
