The Labour Court in Johannesburg is expected to pass judgment on Monday on an urgent interdict that was brought by Amcu to prevent Amplats and Implats from communicating wage settlement offers to mineworkers.
Amcu approached the court last week, seeking to prevent Anglo American Platinum and Impala Platinum from conveying pay offers to striking Association of Mineworkers and Construction Union members, as well as to prevent Implats from conducting surveys of whether employees want to return to work.
Judgment in the matter was reserved on Friday.
At the time, the application against Lonmin was postponed due to Lonmin's participation in a labour court mediation process.
Amcu members at Lonmin, Impala and Anglo American Platinum downed tools on January 23, demanding a basic monthly salary of R12 500.
They have rejected the companies' offer that would bring their cash remuneration to R12 500 by 2017.
The strike has been marred by violence and intimidation. - Sapa
