The South African Teachers Union SADTU has accused the Government Employees Medical Scheme Gems of acting unilaterally and damaging trust with its 800,000 public service members after the scheme announced membership contribution increases for 2026.
The union said on Tuesday Gems has left members feeling trapped in a mandatory relationship with a single medical aid provider.
SADTU said medical aid is a basic necessity in South Africa, and schemes should act responsibly, prioritise member welfare and maintain a mutual relationship of co-operation and trust.
