Thousands of striking workers on BMA's Queensland coal mines are set to return to work but the CFMEU says new negotiations are likely to fail.
AAP reports Construction, Forestry, Mining and Energy Union district president Steve Smyth says while the union will resume talks with BMA on Monday and Tuesday an agreement is unlikely to be made.
"I hate to say it, but I think next week's negotiations will be much of the same," he said.
The CFMEU has again accused BMA of not negotiating in good faith, but the company has denied the accusations and repeatedly said it wants to reach an agreement as soon as possible.
CFMEU national vice-president Wayne McAndrew told ABC News the dispute was of national significance and the national CFMEU office was supporting the Queensland branch in the battle.
"It's an important dispute, not only for up here, but for our union overall," he said.
Earlier this week union delegates from BMA operations gathered in Mackay to show solidarity for striking workers.
At the time the CFMEU said BMA was rumoured to be considering a move to lock-out unionised workers from its mines, a claim denied by the company.
