How Can a Specialty Chemical Company Keep Its Technical Know-How?
A specialty chemical company keeps its technical know-how by recording the reasoning behind each case as work happens, in company records tied to each account. This works when the record shows why a decision was made, not only what was sold, and when the next person on the account can find it without asking anyone.
The median tenure of US wage and salary workers aged 55 to 64 was 9.6 years in January 2026, more than three times the 3.0 years of workers aged 25 to 34 (BLS, 2026).
Among US workers aged 60 to 64, 52.6% had been with their current employer for at least 10 years in January 2026, against 20.3% of workers aged 35 to 39 (BLS, 2026).
Manufacturing workers had a median tenure of 4.9 years in January 2026, among the highest of the major private industries (BLS, 2026).
In January 2026, 20.6% of US wage and salary workers had been with their current employer for a year or less (BLS, 2026).
What does the BLS Employee Tenure in 2026 release mean for company know-how?
The US Bureau of Labor Statistics (BLS) found in its Employee Tenure in 2026 release, published on 24 September 2026, based on a January 2026 supplement to the Current Population Survey, a monthly survey of about 60,000 US households, that long tenure is concentrated in older workers. The median tenure of workers aged 55 to 64 was 9.6 years in January 2026, more than three times the 3.0 years of workers aged 25 to 34 (BLS, 2026). Among workers aged 60 to 64, 52.6% had been with their current employer for at least 10 years, against 20.3% of those aged 35 to 39 (BLS, 2026).
Manufacturing sits near the top. Manufacturing workers had a median tenure of 4.9 years in January 2026, tied with mining and information and behind only financial activities among major private industries (BLS, 2026). BLS notes that these industry differences partly reflect age: the industries with the highest tenure tend to have older workers (BLS, 2026).
The release covers all US wage and salary workers, not chemical companies or technical roles alone, and it measures tenure, not knowledge. The link to specialty chemicals is an inference: in a business where application knowledge builds account by account over years, the people who hold the most of it are, on these figures, also the ones closest to retirement. Movement among younger staff adds to that. In January 2026, 20.6% of wage and salary workers had been with their employer for a year or less (BLS, 2026).
Why does specialty chemical know-how leave with the people who hold it?
Specialty chemical know-how leaves with its holders because most of it is reasoning, and reasoning is rarely written down where the company can find it. The product sold to a plant shows up in the order system. The reasons behind it usually do not: what was tried before it, why the alternatives were dropped and what the customer's engineer accepted.
That reasoning tends to live in personal places: an engineer's memory, a sent-mail folder, a notebook, a spreadsheet on one laptop. Each works for the person who keeps it. None of them is organized around the customer's account, so when the person moves on, the account keeps its products and loses the why.
The cost shows up later and on the customer's side. A new technical rep repeats a trial that was already run, recommends a product the site rejected, or asks the customer for conditions the customer already gave. Senior engineer departures can trigger customer loss, and a new engineer cannot replace a retiring expert one for one, because experience takes years to rebuild while records can be handed over at once.
What does a specialty chemical team lose when a technical person leaves?
When a technical person leaves, a specialty chemical team loses three things that its sales records rarely hold: the open inquiries, the reasoning behind past recommendations and the conditions specific to each customer. Products, prices and invoices stay in the system. These three stay with the person.
Open inquiries are work in progress. A sample out for a trial that has not reported back, a half-answered question about a substitute grade, a promised follow-up on a foaming complaint: each sits in the departing person's inbox and calendar, and the customer expects it to continue without starting over.
The reasoning behind past recommendations is the slowest part to rebuild. Why one grade went in instead of another, which trial settled it and which limit in the technical data sheet (TDS) set the dosage are seldom written into a quote or an order. Without that reasoning, a successor cannot tell a deliberate choice from a habit, and either repeats the work or changes something that was working.
Customer-specific conditions are what make a general product answer fit one line: operating temperature, water hardness, seal materials, cure schedule and the customer's own approval steps. They are learned visit by visit. In January 2026, 52.6% of US workers aged 60 to 64 had been with their current employer for at least 10 years (BLS, 2026). For those in technical roles, that can mean a decade or more of such conditions gathered account by account.
How does a personal record compare with a company record of technical know-how?
A personal record of technical know-how serves its author, while a company record serves whoever handles the account next. The table below compares the two on what a specialty chemical team inherits when someone leaves.
Question | Personal record (memory, mailbox, own files) | Company record (shared accounts, projects, documents) |
|---|---|---|
Who can find it after the author leaves | Nobody, or someone searching an old mailbox | Every member of the team |
What it is organized around | The author's habits | The customer account and project |
What a new rep inherits | Product lists and invoices | Conditions, evidence, decisions and approvals for each case |
What the next similar case starts from | A question to a colleague who may have left | The earlier case document |
The row that decides the outcome is what a new rep inherits. With personal records, the successor receives the products and has to rediscover the reasons. With a company record, the successor reads the earlier cases on the account before the first customer call, and the customer does not have to explain its line again. A handover document for a departing technical rep covers the gap once; a company record closes it for every case.
The organizing row matters for the customer as much as for the team. A plant's maintenance planner who calls about a foaming problem expects the supplier to know which product went in, at what concentration and after which trial. When that history sits under the plant's account, any member of the team can answer, not only the person who ran the trial.
Can a handover interview capture specialty chemical know-how instead?
A handover interview can capture part of a departing expert's specialty chemical know-how, and it is worth doing whenever someone leaves. A structured handover gives the successor the open commitments, the key contacts and the accounts that need attention first. For a retiring expert, a series of recorded conversations about difficult accounts spares the successor much of the rediscovery.
The limit is timing. A handover happens once, at the end, and it depends on what the person remembers and has time to explain in a few days. Reasoning recorded when each case was worked keeps the details that fade: the exact test result, the revision of the safety data sheet (SDS) that was current, the reason a candidate was dropped. The BLS figures also suggest that departures are not only retirements: one in five wage and salary workers had been with their employer for a year or less in January 2026 (BLS, 2026), so some knowledge leaves with people who never get a formal handover.
Customer relationship systems help with contacts and activities, but they hold little of the technical reasoning, the gap described in why a CRM cannot replace a knowledge base. The handover and the running record work best together.
What should a specialty chemical company look for in a tool that keeps know-how?
A specialty chemical company should look for a tool where every record stays the company's and stays connected to the account it belongs to. Five conditions follow:
Every case, document and work log sits in the company's shared workspace, tied to its account and project, and every team member can see it.
The reasoning is recorded as the work happens: the customer's conditions, the evidence used, the conclusion and the person who approved it.
Every answer shows its basis: the company's own TDS, SDS, certificates of analysis and field history.
Each case ends as one document that the next similar case can draw on.
Where information is missing, the record marks it as unconfirmed instead of filling the gap with a guess.
The cost of waiting is know-how the company has already paid for. Every case closed in a personal mailbox is reasoning that leaves with its author, and on the BLS figures the longest-serving staff are also the nearest to retirement.
A team can start with one account or one kind of work, such as turning visit and call notes into customer records. Each recorded case makes the account history richer, and each new team member starts from that history instead of from zero.
