Wow what a toxic attitude. The worst part is acting like this constant crunch time is a normal and reasonable expectation. I'll also call out the derision towards "keeping the lights on" because, of course, keeping the damn lights on is a prerequisite to any kind of growth. Code Yellow doesn't tell people "hey it's not important that the site stay up, just focus on growth instead". It tells people "what you are doing 9-5 to keep the site up is not enough, spend your 5-9 working on this other initiative as well". Evil.
It doesn't feel like it means the same thing to OP as it does to the rest of us:
> The biggest constraint I have seen teams imposing unconsciously is the ‘keeping the lights on’ fallacy. This manifests as the project team giving the project/goal 25-50% of their attention (although saying it is their main priority) because they feel that they need to continue ‘keeping the lights on’ with other work activities or projects.
It sounds like "keeping the lights on" means ... working on other things as well? It doesn't specify that it's to make sure those other things keep working. Maybe it's implied? I have no idea.
