The CSR-owned Sucrogen's seven mills the Mackay, Herbert and Burdekin districts faced problems as its workers walked off over an enterprise bargaining agreement with CSR's sugar arm on Thursday.

The industrial action involves members of the Electrical Trades Union, the Australian Workers' Union, and the Australian Manufacturing Workers Union.

The dispute has not been resolved even after discussions with Fair Work Australia, shared AWU northern district secretary Cowboy Stockholm.

Mr. Stockholm said, “We've been at an impasse for quite some time. I just hope we come to a speedy and amicable solution to the dispute (and) we get a decent outcome for our workers”.

He added that sugar prices have never been better. He shared that workers wish to reach an agreement with management shortly and get the defeat back on track.
