My co-worker developed a medical condition and was fired. Is there any recourse?

North Carolina is an employment-at-will state where you can be terminated for any reason.  You can only file a wrongful termination lawsuit if you can show the termination was motivated by unlawful discrimination or unlawful retaliation. There are no laws that protect employees who are terminated due to medical conditions other than the FMLA which applies only to employers with 50 or more employees or the Americans With Disabilities Act whcih applies to employers with 15 or more employees. Unfortunately, neither law applies to an employer with 10 employees.
