Generally speaking, a restrictive covenant acts to restrict the activities of a former employee after their employment has ended. They usually come in one of two forms: non-competition clauses and non-solicitation clauses. The law on restrictive covenants is that they are prima facie unenforceable as they are in restraint of trade and therefore against public policy. In order to be enforced, they must be proven by the party that seeks to enforce them to be a reasonable limit on trade.
