Miners have again walked off the job at the Tahmoor colliery following pay disputes.
The workers were unable to reach an agreement over pay and work conditions with colliery owner Xstrata at the NSW Southern Highlands mine.
The Construction Forestry Mining and Energy Union (CFMEU) has also accused the mining giant of intimidating workers.
The CMFEU stated that apart from threatening striking workers with disciplinary actions, Xstrata has also sent menacing letters to their homes.
“The letters ask them, obviously, to break ranks with the union, to start off with, and then goes on to say that the reason we haven’t been able to get an agreement at Tahmoor is because of the bargaining committee, the union reps and that we’ve also kept them in the dark,” CFMEU district vice president Bob Timms said.
Xstrata has sought to move the miners from their current work agreements back to previous enterprise agreements.
