More than 80 full time workers have been cut from Anglo American’s Capcoal mine.
Anglo American confirmed the losses.
The job cuts came on the back of a review started last month.
According to the CFMEU, the 85 jobs lost come despite the operation achieving all its set production targets.
“Local workers at Capcoal have shown nothing but goodwill towards Anglo American; through hard work, intensive rostering arrangements and dedication they have met all set production targets,” CFMEU mining district president Steve Smyth said.
“At Anglo American’s nearby Grasstree mine local workers actually broke the world record for underground production on a longwall.
“But instead of thanking their employees the company has rewarded them with the sack; this reeks of a deliberate strategy to attack permanent, secure local jobs,” Smyth said.
“Workers have been told that the issue is overproduction.
“If that was true the company could have simply considered and accepted the union’s alternative suggestions to maintain secure jobs by reducing hours, production, and labour costs," he said.
An Anglo American spokesperson told Australian Mining that as part of the review, in addition to the reduction of positions, "the majority of Capcoal employees [will switch] to a five day, 8.5 hour rotating roster, effective from 5 October".
"All suggestions made by employees and employees’ representatives made during the consultation process as alternatives to the roster change were considered.
"Anglo American has agreed to some of the employee representative's requests, however the proposed roster change remained the most viable option after careful consideration of all suggestions."
Smyth continued to slam the miner, stating: “While 85 secure local roles are set to go, contractors on lower wages and with no job security are being kept on.”
