Onboarding and probation for Medical Plastics Makers: the first weeks at the machine
New joiners are left alone at machines quickly. A structured first weeks plan and probation check keeps them safe, careful and clear on what they may adjust.

A new operator reports at eight, is shown the machine, and by the second week runs a night shift with a helper. Nobody explained the hopper tag, what to do when a part looks short, or who to call when the mould sticks. Clean room joiners pick up gowning from whoever is next to them, and bad habits are copied along with the good ones.
A better start has a day-by-day first week: safety, the layout, the paperwork, then a named buddy for the machine. Probation has set check points, such as end of the first week, first month and the decision point, with the supervisor and setter giving feedback in writing. Clean room joiners are cleared on gowning and handling before they touch assembly work.
How to set it up
1. Prepare before the joiner arrives
Locker, uniform, a buddy and a machine allocation are ready. Collect and file documents on day one, following your HR documentation process.
2. Run a plain first week
Safety, floor layout, material tags, machine start-up and part checks, one item at a time. A supervisor meets the person at the end of each day for five minutes.
3. Give the person a buddy with a limit
A buddy is an experienced operator who answers questions and watches the work. The buddy does not leave the new person alone at a machine until the setter has signed the first stage.
4. Set probation check points
Meet at one week, one month and before the decision. Write down what went well, what needs work and what the person may now do alone.
5. Close the loop on decisions
If the person is confirmed, say so and give the next stage. If not, give a clear reason and the evidence. Avoid decisions made only on the last day.
Check these first
Before changing anything, find out what is true today. These take an afternoon and use your own records.
- Ask the last three joiners what happened in their first week and compare with what you planned.
- Check whether each joiner has a written probation review at the first month.
- Count joiners who ran a machine alone before any sign-off.
- Look at how many clean room joiners left within the first three months and where they worked.

Questions owners ask
Set it to fit the role and what you can see in that time. A helper may show enough within a few weeks, while a setter needs longer on real moulds. Check the legal terms in your appointment letters with a qualified professional.
The direct supervisor with input from the setter or senior operator. HR or the owner keeps the record and checks that reviews happened on time.
Retrain on the specific habit, watch again after a week, and note it. If he still cannot meet the routine, move him to another section rather than risk the batch.
