There's much truth in your post, as I can say from first hand experience. I came out of the burn-out differently than how I went in, changed a lot of things in myself. It was never the workload, it was indeed the environment for me. Me supporting people who didn't have my back when I needed it, in a nutshell.
The social part is very important. Creating that environment of camaraderie at work takes time, but is worth it, if everyone has more or less the same balance of values, and support each other when necessary. As a leader, one can contribute a lot to that, setting the frame for the rest to move within, strict, yet understanding and fair.
Thank you for this post, made me realize that I have actually come a long way in the last 18 months.
