9 Mentorship Traps That Empty Your Plant of Skilled Labor (And How to Fix Them)
A machinist with 32 years of spindle time walks out the door and takes every trick he knows with him. It happens at 60% of plants annually. Here's what separates shops that retain knowledge from those that lose it to the parking lot.
The old guy retires. Nobody wrote anything down. The new CNC operator knows how to load a program but has no idea what to do when the tool chatter sounds wrong or the tolerance stack is creeping. Six months later, he's running scrap.
This is not a skills shortage problem. This is a knowledge transfer failure.
The National Association of Manufacturers estimates that informal knowledge held by retiring workers represents roughly 15% of plant efficiency. When that walks out the door, you don't recover it by hiring a body. You recover it by having built something that works before the person leaves.
