You most likely don't really have any protection, based on what you write:1) If you truly are an independent contractor (I assume that's what you mean by independent contractor), you have no protection against harassment or discrimination whatsover; the workplace anti-harassment/anti-discrimination laws only protect employees, not independent contractors.2) Not all people who are allegedly independent contractors are actually independent contractors--if the employer exercises the degree of control over the alleged independent contractor commonly excercised by an employer over employees (i.e. the "independet" contractor is not "independent" in any meaningful way), the independent contractor is probably actually an employee. But even in that case, protection against harassment is very limited: an employee may not be harassed or discriminated against on account of (that is, based upon or due to) his or her race, national origin, religion, disability, sex, or age over 40--but an employee may be harassed for any other, nondiscriminatory reason, including a "personality conflict" or that the supervisor simply does not like that person. Workplace harassment and bullying is perfectly legal (and unfortunately common) except and only when it is based on one of those few specifically protected characteristics.So unless you are actually an employee and the bullying, etc. is aimed at you because of your race, sex, etc., then the bullying is allowed, and if your employer chooses to let it go on, there is nothing you could do but look for other employment.If you believe that the the bullying and harassment is aimed at you due to a protected characteristic (like race or disabiltiy), then you could contact the federal EEOC or your state equal/civil rights agency to file an employment discrimination complaint.
