You've known for a while. You could name the problem in one sentence if anyone asked.
What you haven't had is the capacity to build the answer — because you're carrying compliance, benefits, employee relations, an integration plan, a headcount plan, and every other operational demand that eats the day before you ever reach the work you actually care about.
So the organization does what most organizations do. It buys training. A workshop. A conference. An LMS full of courses nobody finishes. A leadership program that promises transformation and produces a binder.
Nothing changes, because the conditions never changed.
A manager who sits through a half-day workshop walks back into the same environment — back-to-back meetings, no protected time, no tools to practice with, no safe place to try leading differently. The training didn't fail. The conditions around it did.
