The respondent, Fugro Survey Africa (Pty) Ltd, is a South African company forming part of an international group engaged in geophysical survey work, with a Netherlands counterpart undertaking construction work. The three appellants were construction survey engineers who had been seconded to the Netherlands entity. When Covid-19 occurred, much of the construction work terminated and their secondment was cancelled. The respondent had no construction work in South Africa and was unable to utilise the services of the appellants. The respondent experienced dramatic business impact with a 50% reduction in work and 65% reduction in operational revenue due to cancelled or postponed projects and movement restrictions during Covid-19. The respondent embarked on a consultation process prior to dismissing the appellants for operational requirements. During consultations, various alternatives to retrenchment were discussed, including an unpaid leave proposal whereby the appellants would be placed on unpaid leave (with various permutations regarding salary reduction, medical aid and provident fund benefits) and allowed to work freelance while the respondent marketed their availability within the group and to third parties. The respondent ultimately proceeded with the retrenchments without implementing the unpaid leave proposal.
