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.
6 min readRead articleA PCB factory turns copper-clad laminate into bare circuit boards through imaging, etching, drilling and plating. Wet chemical lines, tight inspection and a few process engineers make people work harder than they look.

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 bare PCB manufacturer takes customer design files and makes boards layer by layer. Inner layers are imaged and etched, the layers are laminated, holes are drilled, copper is plated through the holes, the outer layers are imaged and etched, then a solder mask, surface finish, routing and electrical test follow. Wet process lines use acids, alkalis and plating baths that must be kept in balance. Drilling and imaging rooms are clean and precise. Orders come as small prototype lots and larger repeat runs, each with a delivery date. The process engineer who understands the baths and the operator who can read a defect are the people the plant cannot easily replace. 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.
A bath topped up wrongly or a skipped check on the plating line scraps many boards at once, and the cause is often one tired operator.
Acids, alkalis and plating chemicals demand gloves, aprons and eye wash that work, yet use of protective gear slips on busy shifts.
Bath chemistry limits and the fixes for odd defects sit with one or two engineers, and no one else can read the line when they are away.
Inspectors who look at fine tracks for hours miss faults near the end of the shift, and the customer finds them.
Urgent small lots jump the queue, so lines are reset often and operators work under pressure to keep the main runs on time.
Imaging areas need clean clothing and discipline, and new helpers pick up shortcuts from the shift before them.
Start with the topics that matter most here: Health, Safety and Wellbeing; Learning and Development; Organisation Design. Then work through the rest. Each topic is written for manufacturing, not in general.
Induction, records, incident reporting and follow-through.
Training planned from need rather than from the calendar.
Structure, reporting lines and who is allowed to decide what.
How many people, in which roles, by when — and what they will cost.
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.
Two routes — one for complaints, one for conduct — kept separate.
Policies a manager can apply, and obligations with owners and dates.
Who leaves, when, why — and which of them mattered.
Resignation to relieving letter, in a defined order.
Records that survive people, and approvals that do not queue.
A short monthly pack management actually reads.
An HR function that runs the same way every month.

Use a sign-off ladder so no one runs a line alone before being checked, and keep a short log of bath checks. Review each scrap event for the cause, not the culprit.
Recognise their skill with a distinct grade and pay, give them a say in new equipment and make sure someone else is learning their recipes. Benchmark pay against nearby plants.
Shorter stints, rotation with other tasks and good light. Share defect findings with inspectors so they see why accuracy matters.
Pair each with a senior for the first weeks, show the gear and eye wash on day one and check their handling before they work alone.
Set a daily slot for prototypes, tell sales what it can hold and record what each rush displaced. That gives you facts when a customer pushes.
We would ask who can run each wet line alone, look at the last scrap event, and check the daily chemical safety routine. A good first piece of work is a sign-off ladder for wet line operators plus a recipe record from your process engineers. Scope is agreed in writing afterwards.
