Hundreds of employees at PT Freeport Indonesia are still refusing to resume work in protest at the deteriorating security situation on the road from Timika to Tembagapura in Papua.
Monday's strike follows a spate of shootings by unknown gunmen on Freeport convoys along the road.
The Jakarta Post says the employees, along with their wives are demanding the company, police and the government to solve the security problem.
The women carried banners expressing their concerns about the safety of their husbands, and urged the authorities to immediately address the issue.
The Freeport employees say they would not resume work at the company's giant Grasberg gold and copper mine in Tembagapura unless their demands for a guarantee of safety were met.
At least seven Mimika residents face trial in Jayapura for the attacks.
