I arrived to work on time Monday morning, after clocking in a fellow employee told me, I had been let go Wednesday for no call no show. I was unable to work that Wednesday but had contacted my immediate supervisor in the allotted time to do so.

The plant manager said he had to let me go because of the reason I was not at work. I have never been verbally warned nor written warning. My past review was 2 months prior was above average to excellent. My privacy, and character were both attacked by my superiors. I had followed the written rules given in the handbook issued by the company. I feel discriminated against, and most definitely wrongfully fired. I was working in North Carolina as of today. Any information on how to proceed from here would be greatly appreciated. Thanks for your time.
