What reasons does my employer have offer to fire me?

If you are an at-will employee as most employees are, you can be fired for almost any reason or no reason at all; however, in most instances, employees are fired for insubordination, chronic lateness, incompetence, poor quality of work, failing to follow work rules, low productivity, bad attitude, or just because your employer doesn’t like you (so long as that dislike is not related to an illegal discriminatory reason).
