i went into work and was told to meet manager in his office, manager came in and just handed me a termination form and turn in my badge, i looked at him and said, why am i being fired? He responded i dont have to give a reason its an AT WILL job. I've worked for the company for almost 5 years and was promoted lead in less then 8 months after i was hired, got promoted again to supervisor before hitting the 1 year mark because of my hard work an dedication to my job untill now, i've never been written up or been warned just let go. Is there anything i can do of this situation.
