The company told workers on Friday that the mines would stop producing coal and be put under care and maintenance, leading to the loss of about 500 permanent jobs and possibly opening the door to re-hiring of FIFO labour at a later date, he said.

“Workers are angry and upset about losing their jobs,” Jordan said.

“But people are also looking for clarity about whether Vale intends to resume production at the mines in the foreseeable future and under what circumstances.

“Vale must not be allowed to use a break in production to replace a local, permanent workforce with a casualised, commuting workforce.”

The CFMEU will meet with the company tomorrow before workers are given formal notice about their futures on Friday, Jordan said.

“When big mining companies like Vale stop and start production they are playing with the livelihoods of mineworkers, their families and communities.

“People deserve a full explanation of Vale's intentions.”

“We will be seeking guarantees that if production is resumed at Glennies Creek and Camberwell after a period of care and maintenance, current employees are given first option on jobs.”
