Non-Compete, Non-Disclosure, and Non-Solicitation Clauses in Employment Contracts

Yu Stromberg Cleveland, P.C.

Co-authors: Wallis S. Stromberg and Paul D. Godec

In many of today’s highly competitive industries, information and knowledge truly represent power in the marketplace. Of course, to unleash the power and profitability of the information, employers often must impart proprietary information and knowledge to their employees.

to sign employment contracts containing covenants not to compete, non-disclosure provisions,
and non-solicitation provisions.
