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 requirementsAn engineering plastics processor moulds, extrudes or machines high-performance grades such as nylon, polycarbonate, acetal and similar resins into gears, bushes, housings, rollers and technical parts. These resins must be dried, melted and cooled with care, because a small error in temperature, moisture or pressure changes strength and size. Orders come from machine builders, electrical firms and vehicle suppliers, often in small lots against a drawing, with a sample approved before production. A setter or process technician who knows each resin is valuable, and the unit runs trial shots, measures parts and adjusts before a run begins. For the wider sector picture, read 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.
How long to dry which grade, and what melt temperature to run, is often learned by trial and kept in memory.
Short runs bring repeated trial shots and set-ups, and the process technician is always starting something new.
A badly dried lot looks fine but cracks later, so the fault reaches the customer before anyone notices.
Machinists used to metal burn or crack plastic, and moving them between materials takes patient teaching.
Orders are taken on drawings the shop finds hard, and operators feel set up to fail.
Process technicians with engineering resin experience have few peers and many offers.
Start with the topics that matter most here: Learning and Development; Retention and Attrition Management; Organisation Design. Then work through the rest. Each topic is written for manufacturing, not in general.
Training planned from need rather than from the calendar.

Requisition to joining, the same way every time.
A first day that is the same for the fifth joiner as the first.
Records, attendance, leave and the day-to-day HR that must simply work.
Salary structure, payroll inputs and a month that closes on time.
Goals, reviews and ratings that hold up in a conversation.
Named backups for the roles that cannot be vacant.
Communication, recognition and the conditions people actually work in.

Give a grade, a career step and a say in which orders are accepted. Technicians stay when they are treated as experts, not as extra hands.
Ask the technician to write one sheet per grade with drying time, temperatures and warnings, and have a second person try it. Update it after each problem.
Because they are accepted without the shop's input. A short review of difficult drawings before acceptance keeps promises realistic.
With training. Plastic reacts to heat and feed differently, so a short guided path with checks avoids damaged parts.
Make drying a recorded step with a named owner, and train operators to ask before running a fresh lot.
We would ask your technician which grades only he or she can run, count lots returned for moisture or melt faults and see how hard orders are reviewed before acceptance. A practical opening project is a grade sheet routine plus a technician career ladder. Scope is put in writing after we have spoken.
