I believe non-competes are not favored in Mississippi courts. Because of the underlying reasons for non-competes (to protect the company's interests), I would also think that her employment being terminated (for whatever reason) would nullify or at least inhibit the company's ability to enforce it.
How big is the company? That may play a part in whether they would go to the trouble to try to enforce it. I doubt they go to that trouble unless her new employment directly affects their bottom line. How restrictive is the language of the contract (as in, how specific is it about prohibited activities)? And coach66 is right - if she received some sort of consideration for entering the contract, it's definitely more likely to be enforced. If it was just a condition of employment, though, which she had to accept in order to take the job, it's less likely.

¶ 4. Non-competition agreements have been viewed by this Court as "restrictive contracts [which] are in restraint of trade and individual freedom and are not favorites of the law."
Frierson v. Sheppard Building Supply, Co., 247 Miss. 157, 172, 154 So.2d 151, 156 (1963).
See also Texas Road Boring Co. v. Parker, 194 So.2d 885, 888 (Miss.1967). Only when such agreements are reasonable will they be considered valid and upheld by this Court.
Frierson, 247 Miss. at 172, 154 So.2d at 156. The validity and the enforceability of a non-competition agreement are largely predicated upon the reasonableness and specificity of its terms, primarily, the duration of the restriction and its geographic scope.
Empiregas, Inc. v. Bain, 599 So.2d 971, 975 (Miss.1992);
Redd Pest Control Co. v. Heatherly, 248 Miss. 34, 157 So.2d 133 (1963). The burden of proving the reasonableness of these terms is on the employer.
Texas Road Boring Co., 194 So.2d at 889.
