THE Construction Forestry Mining and Energy Union claims up to 500 people could lose their jobs at two coal mines in New South Wales.
Workers at Glennies Creek underground and Camberwell open cut mines, near Singleton, were warned about the looming cuts last week.
A final decision is expected to be made this week.
Integra, which is a subsidiary of Brazilian mining giant Vale, own the mines which are a major source of local employment.
CFMEU district secretary Peter Jordan told Sky News Australia at the weekend he will be holding talks with the company this week.
"The workers are all in shock at the moment and the anger is starting to set in," he said.
"There is no doubt about that.
"Integra's telling the employees that it is due to lower coal prices and the high Australian dollar.
"We have got 350 members engaged at both the mines and when you add support staff to that you are talking about 500 Integra jobs."
