So sorry to hear of your difficult situation.
I am a lawyer with 25 years experience. While I am not your lawyer and do not represent you, I will endeavor to provide you with legal information through this open and nonconfidential forum.
You appear to have a discrimination
case against your employer but not an unfair labor practices claim. Here is why
Absent a written agreement to the contrary, an employee can be treated differently or discriminated against for any reason, as long as the reason is not prohibited by law. Nepotism is not prohibited by law. However the law does prohibit employment discrimination on the grounds of race, religion, sex, national origin, age, disability,past, current, or future military obligations, FMLA
usage or filing a workers compensation
If you think that your treatment was based one of these protected areas you may have an actionable claim against your employer.
To make a claim against your employer, you must file a "charge of discrimination" with the EEOC
. The charge must be filed by mail or in person with a local EEOC office within 180 days from the date of the alleged violation.
