There's an obstacle that won't resolve through discussion, compromise, or time. Someone is actively blocking progress. Maybe malice, maybe incompetence, maybe conflicted incentives like HAL's impossible directives. Doesn't matter. The obstruction must be removed. You need measure. The text's guidance is critical—unqualified hardness is too violent. Firing everyone, burning the whole system down. Unqualified gentleness is too weak. Endless meetings, hoping the problem fixes itself. You need both: clarity to see exactly what the obstruction is, decisiveness to remove it. The progression through penalties maps to modern disciplinary systems: warning, written warning, PIP, termination. Start mild. If the behavior continues, escalate. The point isn't punishment as an end. It's removing the obstruction so the mouth can close, so union can be established, so actual work can proceed instead of being eternally blocked. Here's the danger in the upper line: becoming the obstruction yourself through obstinate refusal to adapt. If you're deaf to warnings, if you've turned incorrigible, eventually the cangue goes around your own neck. Self-awareness prevents this. Ask yourself: am I removing an obstruction, or am I being obstinate? Sometimes the kindest thing is swift decisive action. The endless performance improvement plan that everyone knows is theater? That's cruelty disguised as mercy. Bite through cleanly. Remove the obstacle. Move forward.
