An improved pay deal will be presented to more than 100 miners working under contract at South32’s Appin colliery on Monday.
CFMEU district vice-president Bob Timbs said the offer from Delta Mining "is better than what was tabled two weeks ago”.
“We’ve been in negotiation with them and they’ve got a further position they want to put to their guys,” Mr Timbs said.
“Delta Mining will be meeting with workforce representatives and rank and file members on Monday morning to table that position to the workforce to see whether that’s acceptable or not.”
A formal vote is expected on January 25.
Miners at Appin have been calling for a better deal for contract employees, one that closes the gap with permanent workers.
Delta is one of several contracting companies at Appin.
He said Mastermyne would table a better pay offer soon while negotiations were ongoing with Southern Colliery Maintenance.
