Changing the explanation for the work separation...be clear, concise and factual
Be careful with verbiage, since false statement penalties exist in many states when providing the actual reason for separation. If a response is inaccurate simply because a mistake was made in choosing the right separation reason, contact the State immediately and clarify the situation. Altering the facts of separation can create monetary penalties and legal ramifications. Just report the actual event leading to separation and the company's position in the matter.
