It seems Qantas PLANNED the grounding last week but didnt ACTIVATE the strategy until Saturday, so, technically, Joyce is correct.............the decision was made after the AGM
Or it could be taken as Qantas PLANNED and DECIDED the grounding before the AGM. After the AGM, the decision (already made) was merely APPROVED by the board.
Either way, Joyce should have warned shareholders at the AGM, the action Qantas would take in response to further threatened union disruption.
