Carol Poole began working as a travel agent for Incentives Unlimited in April 1992. Four years later, Incentives asked Poole to sign an "Employment Agreement" that contained a covenant not to compete. The covenant prohibited Poole from competing directly with Incentives within a four-county-area for one year after ceasing her employment with Incentives. Poole signed the Agreement.
Poole soon left Incentives and began working at a competing travel agency. Incentives sued to enforce the covenant not to compete. The trial court awarded summary judgment to Poole. Incentives appealed. Is the covenant not to compete enforceable? Why or why not?
