The South African National Civic Organisation (Sanco) Gauteng branch has asked its national leadership to report Cosatu and the Nehawu to the South African Human Rights Commission and police for human rights violations.
In a statement Sanco said that as much it believed in the right to strike, it equally recognised that essential workers should not use the sick as bargaining chips.
"We had hoped that the progressive trade union movement would at least show that they cared about patients who are in critical conditions in public hospitals. To our dismay the response of the trade union movement has not been the moral response we expected."
Sanco said it had, therefore, called on its national leaders to take up the cases of those who had lost loved ones because they were denied care in public hospitals.
"Our leadership should request the police and the Human Rights Commission to investigate cases that resulted in lives being lost. The right to life cannot be exchanged for any other right."
