Industrial action will continue for the next fortnight following a workplace agreement dispute between Port Waratah Coal Services and it’s workers.

The action is a response to the agreement, which workers say threatens job security, gives employees less say in shifts and limits avenues to resolve workplace disputes.

NSW Organiser of the Australian Manufacturers and Workers Union, Daniel Wallace, says workers are frustrated and disappointed at the agreement and hope the industrial action will make employers reconsider.

Forgacs workers have joined the action, walking off the job this morning over a pay dispute.

Forgacs says it is trying to remain competitive and sustainable for the future.
