SIT finishes at 0100 year-round.
What's the rationale behind an 8-hour roster as a threat to QF? I know it'll increase time spent on handovers, but can't see any other disadvantage to the company. As far as I know, once you adopt an 8-hour-or-shorter roster the company can dictate the layout of that roster without negotiating with the employees. Sounds like you'd be giving them a lot of power for very little gain.
