can i fight this

I was terminated for missing 5 day in one year. On there perfomance expectations review sheet it is written, "To meet expectations less than 1.5% unexcused adsenteeism and less than 7 occurrences within the last year." This sheet is how the company scores an employee and that determines an employee's raise. Wihin the company's handbook, the attendance policy is very vague and no guidelines are given/ listed.
