QF management are unable to interfere with the PA's as they have been approved by FWA. If management were to interfere then they contravene the FWA ruling and penalties apply.
That's right. Basically QF can allow the ban to go ahead, or espond by lockout - would seem OTT; or not accept the ban - ala the left-hand LAMEs - and not pay pilots that choose to make the union PA announcements.
