Article 81/2021

Labour Edge

What are the consequences of a provision in an agreement recording that the agreement itself contains the entire agreement and that the parties are not bound by any terms, conditions or provisions not contained in the agreement itself?


  1. In this context, the following basic principle was enunciated in Union Government v Vianini Ferro-Concrete Pipes (Pty) Ltd 1941 AD 43 at 47:

‘Now this Court has accepted the rule that when a contract has been reduced to writing, the writing is, in general, regarded as the exclusive memorial of the transaction and in a suit between the parties no evidence to prove its terms may be given save the document or secondary evidence of its contents, nor may the contents of such document be contradicted, altered, added to or varied by parol evidence.’

  1. This is what became known as the ‘parol evidence rule’.

We think that everyone understands that an employer is vicariously liable for the wrong committed (an act or omission) by its employee during the course/scope/sphere of employment/engagement in any activity reasonably incidental to it.

But, what is the extent of an employer’s vicarious liability where the employee commits a wrong on his or her own volition?

What is the content of traditional consensus to indicate that an agreement exists between an employer and an employee?

If, on the traditional theory of consensus, a party fails to prove an agreement upon which it relies, with reference to Sonap Petroleum SA (Pty) Ltd v Pappadogianis 1992 (3) SA 234 (A), on what basis can a finding be made that quasi-mutual assent exists, founded on the approach that a party is precluded from denying the existence of an agreement based on their own conduct and the circumstances?

What does the three-fold enquiry entail to determine the presence of quasi-mutual assent?

In determining whether an agreement has been reached in the absence of traditional consensus, but on the basis of quasi-mutual assent, what is the extent of the duty on the party wishing to rely on such an agreement to, on the basis of reasonableness, enquire as to the contradictions that exist in the position of the other party so contained in correspondence?

Where do delictual claims fit into dispute resolution options applicable to employment disputes?
