This as a good example of how people fail upwards.

If he had listened to us from the onset, this would have proceeded, he would have been maybe casually acknowledged for a solid enough job, business as usual even though the money in play was abnormally astronomical, leadership would have just taken this part of the business for granted.

Because he didn't listen, he created a disaster. Because the disaster had just unimaginably large amounts of money attached with just stupid amounts more potential money in followup business, the executives were panicked. The ability to recover it on schedule suddenly they appreciated it, and he manages to bask in the spotlight.

Ok, so what if we had left him out to dry? We probably would have been fired. He probably would have too, but declining to assist and risking millions of dollars of business screws you too.

The upside? Well, this was noteworthy because this was the first time in many years I had to lose a weekend, so it's not super common. To the extent stuff like this happens more regularly, it usually isn't this bad and is more annoying but on normal business hours. This also happened close to review cycles, and was fantastic relevant information to hold over management so while I didn't get broad recognition, I did walk away with the second largest bonus of my career. Also the project manager learned the lesson and his standard game plan for this sort of thing is now consistent with what we said. He fails upward, but at least he's an ally for the foreseeable future.

The true mark of experience
