We (the devs) pulled it in in a day.
Management congratulated themselves, instead of someone getting sacked for such an epic feat of poor planning.
We were told that they were “worried” that they would “have to” “ask” people to work the weekend.
If management did do something smart it was to hire a large team of battle-hardened contractors who have mostly seen this sort of shit before, and can chuck code over the wall pretty fast.
I think graddy crapped himself and ran away, and someone was crying in the toilets at lunch, but overall most people just rolled their eyes and got on with it.
