Every week, somewhere on a shop floor, someone with thirty years of experience hangs up their work gloves for the last time. They know which machines run hot in summer. They know which supplier to call when the standard one fails. They know things that were never written down, because they never needed to be.
When they leave, that knowledge goes with them. This is the quiet crisis unfolding across manufacturing, and most organizations are underprepared for it.
The numbers are significant
In 2025, a record 4.2 million Americans will reach the age of 65, according to ScottMadden research. In manufacturing specifically, studies estimate that 50% of operations-related roles could face retirement in the next seven to nine years. Between 2024 and 2033, an estimated 2.8 million jobs will be created in the US through retirements alone. Up to 1.9 million of those positions may be difficult to fill, with potential economic losses reaching $454 billion by 2028 according to Deloitte and The Manufacturing Institute.
The 2025 Aging Workforce Study from the Northeast Wisconsin Manufacturing Alliance found that 44% of machinists, 45% of engineers, and 40% of plant managers are already 56 years of age or older. The pipeline behind them is thin.
The succession planning gap
Only 19% of organizations have formal succession plans, according to ScottMadden. And 72% of those that do focus exclusively on executive and senior management, ignoring the operational roles where knowledge loss is most damaging.
A McKinsey survey found that only about one third of critical roles are backed by any succession plan at all. This is not a future problem. It is a present one, playing out in slower troubleshooting times, higher error rates when veterans are absent, and an accelerating loss of institutional knowledge that is nearly impossible to recover once it's gone.

What the companies getting ahead of it are doing
The manufacturers addressing this well share a common approach. They treat succession planning as an operational issue, not an HR formality. That means identifying which roles carry the highest knowledge risk, pairing experienced workers with younger colleagues before retirement becomes imminent, and building structured mentoring programs that make knowledge transfer deliberate rather than accidental.
They also invest in documentation, not in the bureaucratic sense, but in capturing the practical know-how that experienced workers carry: the workarounds, the patterns, the judgment calls that don't appear in any manual. And they take young talent seriously. Newer workers often prioritize growth, purpose, and development above pay. Manufacturers that build those elements into the employee experience are finding it easier to attract the next generation than those still relying on compensation alone.
Key Takeaways
The knowledge walking out the door with retiring workers is often irreplaceable. Making knowledge transfer deliberate and systematic is the most urgent priority.
Only 19% of organizations have formal succession plans. In manufacturing, that gap has direct operational consequences. Succession planning works best when it starts years before a retirement, not months.
The next generation of manufacturing workers has different expectations. Companies that adapt their employee proposition to meet them will have a real recruiting advantage.
