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 hydraulic component maker builds cylinders, pumps and valve blocks that must hold pressure without a weep. The people strain is clean assembly, honing skill and the testers who decide what ships.

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 hydraulic component maker machines cylinder tubes, piston rods, valve blocks and manifolds, hones bores to a mirror finish, chrome plates or induction hardens rods, and assembles units with seals, pistons and fittings in a clean bay. Every unit goes on a test bench for pressure and leak checks. Customers include machine builders, mobile equipment makers and repair shops, buying a mix of catalogue items and custom designs. Honing and seal fitting take years to learn, and one scored bore or a nicked O-ring can bring a unit back from the customer. Related reading: 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.
Finish and size depend on stone choice and feel. A new honing operator scraps tubes before he gains confidence.
A nicked seal looks fine on the bench and weeps under load at the customer's site, so the fitter carries a quiet responsibility.
Grit inside a hydraulic unit shortens its life, yet cleanliness checks are dropped when orders pile up.
A custom bore and stroke needs a new drawing and fresh trials, and a few engineers and fitters absorb the load.
A person who rushes the hold time or accepts a slow seep passes a poor unit, yet the role gets little recognition.
Repair shops send back units without proper facts, and the plant argues over whether the fault lay in making or in use.
Start with the topics that matter most here: Learning and Development; Performance Management; Compensation, Payroll and Benefits. Then work through the rest. Each topic is written for manufacturing, not in general.
Training planned from need rather than from the calendar.
Goals, reviews and ratings that hold up in a conversation.

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.

Start with trial tubes on a set plan, with a senior watching and signing off each stage. Allow some scrap in the plan and fix its limit.
Train and test fitters on the right tools and technique, and pressure-check a sample of units. Keep a list of who is cleared.
Make the check a fixed first step of the shift, with the supervisor signing. If it is skipped once, it will be skipped again.
Give them a small cell and a clear handover when the design is proven, so the standard line runs undisturbed.
Log the unit, its test results and the finding for each return. Share the cases so causes get fixed instead of argued over.
