Anglo American Platinum said that a sit-in protest by about 2,300 employees at its Dishaba mine in South Africa has ended.
The sit-in started following the suspension of an Association of Mineworkers and Construction Union (AMCU) shopsteward, who the company claims had breached safety regulations.
Anglo American said the breach was against its behavioural procedure and in contravention of its Zero Harm objective.
The company said no production has been lost during the strike because safety checks apart from the normal shift work had been planned.
Anglo American Platinum CEO Chris Griffith said that the company encourages employees to raise concerns through relevant channels available and to refrain from participating in illegal activities.
"We will not negotiate with employees engaged in illegal activity especially behaviour and activity that endangers the lives of their fellow workers. Strong action will be taken against those who instigate this type of behaviour and activity," Griffith added.
Dishaba is one of the nine platinum mines 100%-owned by Anglo American Platinum in South Africa.

The refined platinum produced by the mine in 2011 was 161,900oz, compared to 156,000oz during 2010.
