Workers at the Port Kembla Coal Terminal have gone on strike.
It comes after failed enterprise agreement negotiations at the site, where workers demanded a 4.5% pay raise and BHP, the operator of the Port Kembla Coal Terminal, only offered 4.3%.
Close to 100 workers are taking actions at the port, with strikes set to run for the next week, according to the ABC.
CFMEU district vice president Bob Timbs said the initial deal put forth by the coal terminal was knocked back and industrial action almost a given
Speaking during negotiations last week, Timbs said "if we can’t come up with an agreement, we’ll be shutting down the Port Kembla Coal Terminal for seven days.
"Port Kembla Coal Terminal management, under advice by BHP Billiton, are trying to have some jobs which are under the agreement removed," Timbs said.
"The other thing [we are demanding] is some certainty on manning levels."
While coal terminal general manager Peter Green refused to comment on the stumbling blocks in the agreement, he did say that negotiations are continuing.
Despite industrial action at the site, West Cliff coal miners have called off industrial action over their ongoing pay disputes.
