The decision in Gerhard Potgieter Maintenance Services (Witbank) (Pty) (Ltd) v Contract Cleaning National Provident Fund and others [2020] 9 BLLR 889 (LAC) is instructive particularly the following paragrraph:
“The compulsory nature of membership of the fund ……… serves a rational purpose, ie to secure a critical mass of contributors in one pool. Indeed, the pooling of risk is the fundamental element of any provident fund, a commonplace example of collective sharing of risk. If a member could join and leave at will for better schemes the risk that the residue would be diminished to a point where the scheme would be unviable is plain. Imposing a compulsion to belong serves to eliminate that risk. It serves the interests of the most vulnerable employees.@
I therefore suggest that employers would have to apply for an exemption.
