I can't remember whether it was the late 60's or early 70's but there was a huge strike in the mines at Mt Isa. Turns out that it would have cost management an enormous amount to stand people down while they went through an equipment upgrade. So, as the story goes, the strike was formented, no one was paid and the equipment was changed out and the workers were screwed a couple of weeks pay.
The reason I say this is that it almost appears that a strike is being encouraged at NJS.
And on a separate subject, in this case pilot seniority really works well for the managers by making it very difficult for senior crew to change jobs.
