Definitely with Ollie, Studentindebt, burnt_out etc on this one.
If there isn't enough time to brief after report, then there isn't enough time. 99% of the time its sufficient.That 1% then the flight departs late, so be it. Safety before OTP. If they want 100% OTP the airline can pay for me to come in earlier.
Bet if if they reduced your report time to near nothing you'd be up in arms! (i find it odd that some are not already about a 15 min briefing time! How is that safe?)
