If my direct supervisor comments about my weight several times is that harassment? I have also gotten let go from said job because "you don't fit in"

   Harassment is unlawful in North Carolina only if it is directed to you on the basis of an unlawful factor such as race, color, sex, national origin, religion, disability or age, 40 or older.  Harassing someone because he is overweight is unfair, but not unlawful.   Further,  NC an employment-at-will state which means you can be fired for any reason and there is no liability for the employer unless there is an unlawful motive for the action taken against you. There are generally only two forms of unlawful motives: unlawful discrimination or unlawful retaliation. Discrimination in employment is unlawful if it is due to race, color, sex, national origin, religion, disability or age 40 or older. Again, firing you because you are overweight is unfair, but not unlawful.  However, it does give me pause that she mentioned your arm braces.  The Americans With Disabilities Act (ADA) prohibits discrimination against employees or applicants for employment due to a disability.  The ADA also requires an employer to provide a reasonable accommodation to an employee or applicant with a disability that will allow the person to perform the essential functions of the job.  While it is a stretch, if she thought you had a disability, or you actually have a disability, and she fired you because of the disability or her belief that you had a disability, then that could be unlawful.
