Consideration

Jackson was hired to sell consulting services for Acme Accounting and was promoted to manager four months later. A short time after the promotion, Jackson was required to sign a non-compete agreement. When the business suffered financially, Jackson joined with a former employee to create an accounting firm that also solicited clients for consulting business. Acme sued Jackson to enforce the agreement.

What was the consideration for signing the non-compete agreement? If you find consideration, was it adequate?

Would your answer change if Jackson had to sign the non-compete at the time of his promotion?
