North Safety Products v Marshall Naidoo and Brian Pienaar North Ltd t/a Pienaar Bros (Pty) Ltd

The Applicant (North Safety Products) designs, manufactures and markets personal protection and safety equipment. The First Respondent (Marshall Naidoo) was employed by the Applicant as a Sales Representative in Richards Bay from 6 July 2017 until he resigned at the end of May 2019. He left to take up employment with the Second Respondent (Brian Pienaar North Ltd t/a Pienaar Bros (Pty) Ltd), a competitor, as its Key Contracts Manager. The First Respondent had signed restraint and confidentiality undertakings. The Applicant sought to enforce these undertakings for 12 months within Richards Bay. The Applicant claimed the First Respondent possessed unique knowledge of customer needs and specific requirements obtained during employment. The First Respondent had worked for 12 years in personal protective equipment manufacturing before joining the Applicant for just under 2 years. He denied having unique knowledge specific to the Applicant, stating his product knowledge came from his prior extensive industry experience. The Applicant specifically cited two major clients (Rio Tinto and South 32) that would be tendering for PPE contracts in late 2019 or early 2020 as examples of clients at risk.

• Whether the Applicant had a protectable interest in customer connections
• Whether the Applicant had a protectable interest in trade secrets or confidential information
• Whether the First Respondent's knowledge of customer preferences constituted confidential information or merely recollected knowledge and general industry experience
• Whether the restraint of trade agreement should be enforced
• How to distinguish between trade secrets and general recollected knowledge and experience acquired during employment

The application was dismissed with costs.

1. An employee is free to use and disclose general recollected knowledge acquired during employment in his own interests or in the interest of a new employer who competes with the former employer. 2. Knowledge of customer preferences, purchasing history and specific requirements acquired during employment generally constitutes recollected knowledge rather than confidential information or trade secrets. 3. A trade secret typically contains specific knowledge formulated by an employer and conveyed to an employee, often documentary in nature, and is knowledge transmitted as an important tool rather than passively acquired. An employer has no protectable interest in recollected knowledge, insights, experience and increasing acumen acquired by an employee during employment. 4. To establish protectable customer connections, an employer must prove the employee had contact with customers sufficient to get them 'strongly attached' such that the employee would 'automatically carry the customer with him in his pocket' when leaving for a competitor. 5. Information that becomes public knowledge through tender processes cannot constitute confidential information warranting enforcement of a restraint.

The Court made observations about the nature of trade secrets, noting that a key element is genesis - it is not knowledge passively acquired while working but knowledge formulated by an employer and transmitted to an employee. The Court observed it would be 'unreasonable, verging on dystopian' to expect employees on exit to purge recollected customer information from their memory or else suffer impairment to their right to freedom of occupation. The Court commented that 'all too often, wide and generalized allegations of potential harm are made in restraint proceedings' but that concrete examples allow proper assessment of actual risk. The Court noted that logic would dictate customers would want the two suppliers who best understand their needs to compete on price in tender processes.

This case provides important guidance on distinguishing between protectable trade secrets and general recollected knowledge in restraint of trade disputes. It reinforces that employers cannot restrain employees from using general industry knowledge, experience, acumen and recollected information acquired during employment. The judgment protects employees' constitutional right to freedom of occupation by narrowly defining what constitutes protectable confidential information. It establishes that knowledge of customer preferences and purchasing history generally constitutes recollected knowledge rather than trade secrets. The case also demonstrates the application of the Plascon Evans rule in restraint of trade applications, requiring applicants to specifically address factual assertions made by employees. It provides practical guidance on customer connection cases, requiring proof that customers would readily follow the employee rather than speculation they 'may well' do so.
