ABOUT 4000 workers will be on strike for a week after they have walked off the job at BHP Billiton's central Queensland mines at 6pm when shifts changed over.
The workers at BHP's seven Bowen Basin mine sites agreed to go on strike after enterprise bargaining negotiations broke down this afternoon.
It is the latest move in a 15-month industrial dispute; last month workers went on strike for a week.
Construction, Forestry, Mining and Energy Union (CFMEU) spokesman Steve Smyth says the company yesterday proposed changes to some areas in which agreement had previously been reached.
He said the strike was expected to last seven days.
