Told To Ignore A Subpoena

I have been subpoenaed to testify in a DV criminal assault case in which my daughter and I were victims at the hands of my son-in-law. I requested and was granted a day off from work. Since then, I have resigned from my job as a therapist at a Community Mental Health Agency. It is the company’s policy that no PTO/leave will be granted during the transition time. My supervisor sent me an email that I am required to attend a training at the same time as the court case. I was reminded I was an “At Will” employee and that failure tonight comply with this requirement could result in termination. Can the agency do that? Fire me for complying with a subpoena? I’m unsure of what to do next. How do I alert my supervisor’s supervisor that I am being asked to ignore a subpoena. If I do not attend court, what could happen to me? I’m in North Carolina.
