More than 500 miners have now spent three days underground at the Gold One mine in Springs in a dramatic stand-off over union representation that threatens to descend into violence.
The impasse was set in motion on Sunday night by the Association of Mineworkers and Construction Union (AMCU), backed by several hundred workers, who demanded that the union be recognised by mine bosses.
This would upend a legacy recognition agreement with the National Union of Mineworkers in place since 2012, who claim their members are being held against their will.
