A slain Association of Mineworkers and Construction Union leader received death threats before he was killed, the union says.
A North West regional organiser of trade union Amcu was shot dead in Rustenburg on Saturday, police said.
With Amcu’s rise to power, companies are trying to give other unions a better chance.
The fledgling union is not just at odds with the National Union of Mineworkers – it is up against the entire state machinery.
