I took a seasonal job over the summer after talking with my boss. He said I could stay employed and work on Saturdays and come back after the summer. A week later I got a letter saying I quit without notice. He was fired shortly after. I just found out today that someone in his office is saying (during a reference check) that I was terminated. I called the HR department to verify what my file stated, she said it states I quit without notice. What can I do?
