The Case
Burnout isn’t a culture problem. It’s a physiological performance problem.
Your senior team is operating with chronic sleep debt, dysregulated nervous systems, and no recovery infrastructure.
The cost shows up in poor decisions, lower output, increased sick days, and quiet attrition of your highest performers.
This is where
performance systems begin.
