I need to know about labor laws. my husband is being what I day abused by his employer but cant afford to quit until he finds another job.

It's difficult to answer your question without more specific detail, but I'll give you an overview:  If the employer is harassing and/or discriminating against your husband because of his age, race, sex, national origin, disability, or religion, then the employer is violating the law.  If your husband is being abused/harassed because he is a whistleblower, or complained about terms and conditions of employment, or took a medical leave, he may have legal protection.   However, if this is a personality conflict between your husband and his supervisor, there is not much you can do.   There is no law against an employer behaving like a jerk. If your husband believes he is legally protected, he should document the incidents of harassment and contact an attorney.
