Management at platinum giant Lonmin's Marikana mine in South Africa, the scene of deadly violence in August, said some workers had renewed a work stayaway on Thursday amid allegations of police harassment.
"We are experiencing disruption," said Sue Vey, a spokesperson for the London-listed firm, which was rocked by the police killing of 34 workers on August 16.
"It is too early to call it a strike. Some people have not been underground this morning as they were expected to be," Vey said.
The stoppage appears to have been prompted by workers' anger at a series of police arrests in recent days.
"The guys are concerned," said Zolisa Bodlani, a worker representative. "There were some guys that were arrested during the weekend."
Workers are expected to gather later in the day and deliver a memorandum to managers to "show their concern about those guys that were arrested," Bodlani added.
Employees at the mine have been back at work for almost a month, after the worst violence seen in post-apartheid South Africa prompted management to agree a substantial pay rise.
In all 46 people were killed, both workers and police, over weeks of violence that are now being investigated by a government-appointed commission of inquiry.
The panel, led by a retired judge, is expected to resume deliberations on Monday.
