Short answer first. Fix the opening ninety days. Make rosters look even-handed. Let a trimmer or packer see how to reach a machine. Explain the wage slip. Money matters too, yet in most plastics units it is not the first lever, and a raise alone seldom holds people who are quitting over the rest.
The fuller answer begins with locating the leak. A plant that loses packers in week two needs a different remedy from one that loses machine attendants after a year.
Locate the leak before spending anything
One attrition percentage for the entire works conceals nearly everything useful. Group line workers by joining month instead. Each row records how many arrived and how many survive at fixed checkpoints. Within a season the shape becomes obvious.
Joining month, for instance April.
Headcount joined that month, split by job: trimmer, packer, sorter, helper, machine attendant.
Remaining at day thirty.
Remaining at day ninety.
Remaining at day one hundred and eighty.
Shift and machine group where most leavers worked.
Main reasons heard from leavers, in their own phrasing.
What was changed for the following cohort, and from which date.Plastics plants that keep this table usually see the sharpest fall before day ninety. That points to induction, rostering and the first wage packet. Where the fall comes later, examine the route to machine work and the pay structure.
Four levers, pulled in sequence
- 1
A planned opening quarter
Safety walk past hot sprues and the granulator, a named buddy, a single bench to begin, daytime hours for the first month and brief check-ins at day seven, thirty and ninety. Our first-thirty-days onboarding guide lays it out in detail.
- 2
Rosters that look even-handed
Put the rota on the board a week or more ahead, rotate C shift so it never becomes a permanent posting, and share overtime from a visible list.
- 3
A route from bench to machine
Spell out what a packer or trimmer must demonstrate to become a machine attendant, whose signature confirms it, and how pay changes. Display it beside the rota.
- 4
A wage slip explained face to face
On a newcomer's first pay day, the accounts clerk goes through the slip in the worker's language: days present, overtime, incentive, canteen tokens, uniform recovery and any advance. Pay on the promised date, every month.
What leavers tend to say once they feel safe
- Nobody said the bay beside the presses would be this hot, or that standing all shift on bare concrete was normal.
- The rota changed overnight and a cousin's wedding was missed.
- A trimming knife slipped, and the only response was a scolding for slowing the line.
- Deductions appeared on the slip that nobody could explain.
- Workers who joined later were already learning the press.
Each remark maps to a lever above. Heat and standing belong to the opening quarter, the wedding to rostering, the knife to induction and supervision, and the slip to pay. Sorting comments this way turns grumbles into a to-do list.
Will a higher daily rate solve it?
Occasionally, especially where your rates trail the industrial estate. Compare against a local benchmark before deciding. A raise cannot soothe a scalded wrist on day two, explain a baffling slip or undo nights imposed in week two. Plants that lift wages and leave everything else alone often watch the same people depart a little later. Our deep-dive on churn at the packing end explains how much the job design itself drives this.
And contractor-supplied workers?
They frequently go sooner, partly from uncertainty about their future at the unit. Their terms sit with the contractor, yet floor treatment sits with you: the induction walk, a buddy and even-handed rostering cost nothing extra. Keep them as a distinct cohort so their exits show up instead of vanishing into somebody else's headcount.
How soon will results show?
Typically within a few joining cohorts, provided the change targets the right stage. The plant-wide number lags, because it blends veterans with newcomers. Compare each fresh cohort's ninety-day column with those recorded before the change. Why the headline figure misleads is unpacked in what a standard attrition calculation leaves out.
Who should own it inside the plant?
Whoever files joining papers maintains the tracker. The production manager owns rosters and the bench-to-machine route. Accounts owns the slip walk-through. The proprietor reads the table monthly and asks what moved. Where nobody has the hours, GullyHR's retention support can set it up and hand it over.
Five things to do this week
- Assemble a year of cohorts from the joining register and the attendance muster.
- Read the latest ten exit notes, or phone a few recent leavers if no notes exist.
- Check who is on C shift this week and how many weeks each has been employed.
- Ask three packers what they would need to show before running a press.
- Look at a newcomer's first wage slip and try explaining every line yourself.
