alt Hacker NewsI think there's a pretty clear and wide gulf between "nobody could have seen that coming", or "I just wasn't on my A game", and frank negligence.
I once worked at a very large company, and one of my coworkers was like "eh, I'm not going to do any of this work, because I don't have to", and that was a clear indicator that the problem wasn't (just) with the system, but with him individually.
I've had a similar experience, also at a very large organization. In my case this person chose that kind of environment because it allowed them to work on side stuff while waiting for approvals, etc. A lot of people in very large companies don't view the grind of organizational friction inhibiting their actions as problematic.
