ANSWER: For the most part, an employer is free to even fire an at-will employee who misses too much time from work since attendance is a basic job requirement for most positions. However, if your absences are protected by the Family and Medical Leave Act, the Americans with Disabilities Act, workers' compensation laws, then your employer can't fire you because of them.
I know this is not the answer you wanted to hear, but I am assuming that you wanted a professional and honest answer.
