The MUA have been locked out since Tuesday, after introducing a Fair Work Australia sanctioned ban on unscheduled overtime.
Patrick stevedores have locked out their 26 strong Dampier workforce after pay talks stalled with the Maritime Union of Australia (MUA).
MUA organiser, Doug Heath, says the lock-out follows 22 months of difficult talks over a new Enterprise Bargaining Agreement.
“Patrick haven’t had genuine intent to negotiate through that period,” he said. The Dampier Port Authority says the lock-out is starting to affect operations at the port.
