Why manufacturing employees leave and how to understand why
Operators, technicians and supervisors leave for reasons that sit in shifts, skills and supervision. How to ask, read the pattern by shift and act on it.

Not sure what you need? Tell us about your business in six short steps and we will come to the first meeting prepared.
Share your requirementsA resin manufacturer cooks polymers such as phenolic, polyester, alkyd or epoxy types in heated reactors, with long batch cycles that run through shift changes. Raw materials are charged by weight, heated, held and sampled until the viscosity, acid value or colour is on target, then cooled, thinned and drained into drums or tanks. A batch can take many hours, and the result depends on timing, temperature and the operator's call on when to stop. Grades change often, and cleaning a reactor between them is slow. Customers in coatings, laminates, foundries and moulding run their own lines on the resin, so a late or off-grade lot stops them. The plant needs a few experienced cooks, steady shift handovers and careful handling of heat and fumes. See also HR for manufacturing.
These are the places the people side of this kind of business tends to give way. The rest of this page works through them.
HR here has to work for each of these groups, not only the office. The set-up below is written with all of them in mind.
The outgoing cook knows the batch is slow and the incoming one finds the reactor at a different stage with only a note.
They know when a batch is near the end point before the test is back, and newer staff overshoot or stop early.
Hot reactors and vapour at charging and draining lead to dizziness and absence, especially in summer.
A slow clean down between grades is rushed when the order book is full, and the next lot is contaminated.
Waiting on a test holds the reactor and the shift, and cooks learn to guess instead of wait.
The plant loses its best hands and gains a supervisor who has not learnt to manage a crew.

Use one batch log that moves with the batch, read aloud and signed by both cooks. Allow overlap time in the roster.
Put a named trainee beside a senior on every long batch and sign off each resin stage. Allow time, as this skill builds slowly.
Link it to the resins a cook is signed off to run alone. Check the level against comparable local plants.
Shorten exposure with shared turns, give water and rest points and check gear. Arrange health checks through a qualified doctor.
Only if they want it and are prepared first. Keep a senior technical grade as another path.
We would read recent batch logs with you, count how many cooks can run each resin and ask what your senior cook notices before the test. A good first piece of work is a handover log and a cook grade ladder. Scope is then agreed in writing.
