Can you be fired for not following company rules and/or guidelines when no such rules/guidelinesnwere provided?

Asked in Gainesville, GA - 8 months

I was told I was fired because "you do not fit in here" after a year and two months of employment. However after filing for unemployment benefits, the employer came back with I did not follow company rules and guidelines. However, no company rules/guidelines, policies or procedures, attendance policies, Employee handbook, Insubordination, Internet policy were ever provided, even when requested. Also, stated that I never performed the job duties I was hired to do, when I was verbally told on two separate occasions how well I had learned my job, the systems and programs and how my fellow co-workers praised my work; and how I now knew the systems better than the ceo, stated by the ceo. I also have in an email train from the ceo that my job performance was good, then marginal to unacceptable
