A non-solicitation clause is a provision in a contract generally prohibiting the hiring (or attempting to hire) of one of the other party’s employees or contractors. It can be thought of as an “anti-poaching” provision. Often, vendors will add such a provision to keep its customers or clients from poaching the vendor’s employees in an attempt to avoid using the vendor by bringing the vendor’s expertise in house. When this happens, the vendor loses not only a key employee, but also, in many case, a client.
