The PPU only exists to go on strike. They were formed by a disaffected bunch that weren't marched out on strike when they were desperate to do so. They HAVE to go on strike otherwise their whole reason for existence becomes irrelevant. It doesn't matter what the issue was, they'd call out a strike regardless.
However, the Company know all the above and will play their cards accordingly. The end result will not be to the greater good of the VS pilots.
What a shame.
