“I cannot find any case in which a covenant against competition by a servant or apprentice has, as such, ever been upheld by the Court. Wherever such covenants have been upheld it has been on the ground, not that the servant or apprentice would, by reason of his employment or training, obtain the skill and knowledge necessary to equip him as a possible competitor in the trade, but that he might obtain such personal knowledge of and influence over the customers of his employer, or such an acquaintance with his employer’s trade secrets as would enable him, if competition were allowed, to take advantage of his employer’s trade connection or utilise information confidentially obtained.”
“The employer’s claim for protection must be based upon the identification of some advantage or asset inherent in the business which can properly be regarded as, in a general sense, his property, and which it would be unjust to allow the employee to appropriate for his own purposes, even though he, the employee, may have contributed to its creation.” (5) If, however, the Court is to uphold restrictions which a covenant imposes upon the freedom of action of the servant after he has left the service of the master, the master must satisfy the Court that the restrictions are no greater than are reasonably necessary for the protection of the master in his business: (see Mason v. Provident Clothing & Supply Co. Ltd.[1913] AC 724 at p.742 per Lord Moulton). As Lord Parker stressed in Herbert Morris Ltd. v. Saxelby (supra) at p.707, for any covenant in restraint of trade to be treated as reasonable in the interests of the parties “it must afford no more than adequate protection to the benefit of the party in whose favour it is imposed” [Lord Parker’s emphasis]”
“any person firm or company who or which shall at the Termination Date be negotiating with”
“… a suitably drafted covenant precluding the defendants, for a reasonable period of time after the termination of their employment, from soliciting or dealing with clients of the plaintiff with whom they had dealt during the period of their employment, would appear to have been quite adequate for the plaintiff’s protection …” (ii) Moreover, the clauses are not limited to those customers in relation to whom Mr. Ayris worked indirectly (such as preparing proposals) in a time proximate to the termination date. …”
“(3) While the employee remains in the employment of the employer the obligations are included in the implied term which imposes a duty of good faith or fidelity on the employee. For the purpose of the present appeal it is not necessary to consider the precise limits of this implied term, but it may be noted: (a) that the extent of the duty of good faith will vary according to the nature of the contract (see Vokes Ltd. v. Heather); (b) that the duty of good faith will be broken if an employee makes or copies a list of the customers of the employer for use after his employment ends or deliberately memorises such a list, even though, except in special circumstances, there is no general restriction on an ex-employee canvassing or doing business with customers of his former employer (see Robb v. Green[1895] 2 QB 315 … and Wessex Dairies Ltd. v. Smith[1935] 2 KB 80 …”
