A week and a half isn't crunch though, I'm talking about sustained long hours over a month or more(usually 4-6 months).
Working a strong week is totally fine if followed by some recovery time. As long as it doesn't go longer than 2 weeks that's possible to do without destroying productivity, although you still run the risk of burning out your employees.
I think the original idea of 'crunch' is that short period but games (and, in my experience, vfx) tend to just normalize that constant long hours (though they'll hire you saying that hours only get bad at peak times without mentioning that it's always a 'busy' time).
