Lodown,
pilot seniority really works well for the managers by making it very difficult for senior crew to change jobs.
True, but it also works the other way, because if there was no seniority in the industry, there would be on impediment to all the senior pilots leaving and absolutely stuffing the organisation. Look at the engineer movements around the industry. If the pilots did the same thing, I suspect that they would all still have jobs, and outfits like NJS would have no aeroplanes flying because evrybody would have left to go down the road. Can you imagine what would happen when DJ starts up it's Perth base with direct entry commands?
So managers had better appreciate the seniority system.
