The South African Transport and Allied Workers Union (Satawu) said on Wednesday a court interdiction secured by the national ports authority has stopped planned strike action at ports from Thursday.
"Transnet National Ports Authority has interdicted the strike and the Labour Court has reserved judgment until Sept. 5, meaning we cannot go on strike tomorrow," union spokeswoman Zanele Sabela said.
The strike was called after a deadlock over salary discrepancies between white and black workers.
