UWV's public-sector signal matters for small companies too: a role can be refilled faster than the judgement behind it.
Retirement is usually counted in people. One colleague leaves, one vacancy opens, one replacement is needed. That is tidy enough for a spreadsheet, but it is too tidy for real work. That makes Dutch sickness records a record of trust, timing and reintegration, not only an HR note.
When the record carries the case
In a company, retirement often removes something less visible than a person. It removes memory. It removes judgement. It removes the colleague who knows which exception is harmless, which client promise was made three years ago, which system workaround is risky, and which supplier always needs one extra check before payment.
UWV's 2026 employer research makes public administration the clearest Dutch case. In that sector, 89 percent of establishments expect retirement outflow within five years. Among those employers, 67 percent expect this to become a problem to a reasonable or high degree. Across sectors, employers point not only to replacement needs, but also to loss of experience, knowledge and skills.
The real issue is not simply whether younger people arrive. It is whether the organisation can transfer enough judgement before older specialists leave.
What retirement actually removes
A small business owner will recognise the pattern immediately.
Imagine a company with twelve employees. One senior administrator has handled invoicing, payroll questions, supplier habits and awkward client exceptions for years. She retires. A capable new employee starts. The tasks are listed. The software access is arranged. The desk is occupied.
Then the friction begins. One customer pays late unless the invoice reference follows an old format. One supplier discount depends on a personal contact. One recurring payroll question has a history that never reached the handbook. A compliance step was always done, but only because the senior employee knew when to pause and ask.
Nothing collapses. That is why the risk is often missed. Instead, the founder receives more small questions. Credit notes rise. Decisions slow down. Junior staff become careful in the wrong places and confident in the wrong places. The company still has headcount, but its internal judgement layer has become thinner.
Payment pressure meets privacy
This is why retirement belongs in the same conversation as onboarding, delegation, work design, access rights, process documentation and quality control. It is an HR issue, but not only an HR issue. It touches cash flow, service reliability, compliance discipline, client retention and the owner's own workload.
A cooler labour market does not create experience
CBS reported 378,000 open vacancies at the end of the first quarter of 2026, with labour-market tension at 91 vacancies per 100 unemployed persons. That is less extreme than earlier peaks, but it is not a calm labour market. Public administration still had 22,400 open vacancies in the first quarter, while the sector added 6,000 jobs.
Vacancy figures do not measure embedded knowledge. A vacancy can be filled while the work remains fragile. The new person may be intelligent, motivated and well trained, yet still need months to understand why certain decisions are made in a particular way.
UWV also reports that 52 percent of employers with vacancies in the previous 12 months more often hire people who still need training because of labour-market tightness. That changes the role of experienced employees. They are not only doing the work. They are part of the production system that turns new hires into competent colleagues.
If that mentoring role is not planned, the company hires capacity without transferring competence. That is expensive, even when it does not appear under one neat cost code.
The planning calendar is already visible
CBS reported that more than 100,000 employees retired in the Netherlands in 2025. The average employee retirement age was 66 years and 4 months. Rijksoverheid states that the AOW age is 67 in 2025, 2026 and 2027, and 67 years and 3 months from 2028 through 2031.
The AOW age does not tell an employer exactly when a person will retire. Actual timing depends on pension choices, health, finances, work arrangements and employment conditions. But it does give a planning rhythm. The Dutch retirement horizon is not a surprise event.
For a small employer, the useful question is not who is old enough to leave. The better question is which work would become slow, unsafe or founder-dependent if one experienced person stopped tomorrow.
That question points to the real control points. Who knows the exceptions? Who holds client history? Who understands the payroll detail that always causes confusion? Who has authority in practice, even if the organisation chart says something else? Who knows which system setting is dangerous to change?
Those answers are often not found in job descriptions. They sit in people.
Do not waste the final handover window
There is another quiet risk: experienced people spend too much of their final working period on the wrong work.
What employers should keep readable
DNB reported in April that Dutch workers say they spend, on average, one fifth of their working time on tasks they do not regard as core tasks. Meetings and administration are prominent, especially in education and government. For employers facing retirement pressure, this matters. If the most experienced people spend their last years absorbed by low-value internal load, the organisation wastes the very period in which knowledge transfer should happen.
A sensible response is not to turn every senior employee into a walking manual. Some judgement cannot be flattened into a checklist. It can, however, be made more transferable.
Pair experienced and newer employees on live work, not only on training sessions. Real files show the exceptions. Ask the senior colleague to explain why a decision is made, not only what button to press. Protect time for mentoring. Review access rights so that knowledge sharing does not weaken confidentiality. Treat documentation as a living working tool, not as a farewell project in the final month.
AI may help structure notes, process maps and training material, but it does not replace judgement. UWV reports that many employers expect more AI use within five years, while guidance and preparation lag behind. A company that uses AI to document weak routines may simply preserve old mistakes more efficiently.
Retirement is not a crisis if it is treated early
There is no need for drama here. Retirement is part of working life. Many companies handle it well because they talk early, respect the person leaving, and give younger employees real responsibility before the last day arrives.
The problem starts when employers treat retirement as a payroll date instead of a knowledge handover. By the time the farewell drinks are on the calendar, the best transfer window may already be gone.
For founders and small employers, the smallest useful step is also the most honest one: choose one critical process and ask who really knows how it works. Then ask where that knowledge lives, who else has performed it, and what would happen if that person were absent for three weeks.
That question will not solve retirement pressure in one morning. But it will show whether the company has turned experience into a working routine, or whether too much of the business still leaves through the door with one trusted colleague.
