I do greatly appreciate my management and general company tech culture, they're great.
I agree with your stance here, because it's part of my point. I tend to see more people bitching about Agile itself and not management or their particular implementation.
The jobs where I was only given enough info to plan 2 - 4 weeks out were so stressful because I frequently felt like I was guessing at which work was important or even actually relevant. Hated it.
Turns out it's a skill issue ;p (on the management level to be clear). Folks, don't let your lazy managers ruin you on a system that can be perfectly fine if done right.
