"The Fair Work Ombudsman also alleged that company had breached workplace laws by applying duress to two pilots in an effort to pressure them into signing workplace agreements.

Looks more like this was about "Workchoice Legislation" than CPI increases. Perhaps the focus was lost somewhere during the case.
