Onboarding and probation for Battery Pack Makers: getting fast-growth hires safe and productive
Fast growth brings untrained hires into a work area where mistakes are costly. An onboarding and probation plan teaches the safety habits first and the skills next, with sign-off at each step.

Share your requirementsWhy onboarding and probation matters in battery pack makers
When orders grow, new hands join on a Monday and are put on the line by Tuesday. The first task may be cell sorting or spot welding, and the supervisor, who is behind, gives a brief demonstration. The person does not know the rules for terminals, tools or damaged cells. A grading error or a weak weld may show up only at final test, or in the field. Some new hires quit after a scare, others stay and repeat a bad habit.
Good looks like a first week that is the same for each person. Day one covers the cell hazards, the gear and the exit. Skills are taught in order, with a trainer watching the first packs and signing off each step. Probation sets a few clear tasks and a date for each, and a supervisor decides on evidence. A new hire is not alone near live cells until signed off.
How to set it up
1. Set a safety-first first day
Before any work, cover cell hazards, tools near terminals, the damaged cell bin, the exit route and the heat response. Test understanding by asking, not by reading a notice.
2. Teach skills in a fixed order
Start with cell handling and grading, then welding, wiring, protection board fitting and testing. Each person moves on when a trainer signs off the previous step.
3. Assign a named trainer
Choose a careful senior operator for each new hire. Give the trainer time and recognition for it. Our onboarding work helps set up the sign-off sheet.
4. Review at the end of each week
Meet briefly to ask what is unclear, what felt unsafe and what skill is next. Record the answers on the sign-off sheet.
5. Decide probation on observed work
At the end, look at the sign-off sheet, the quality of packs and attitude to safety. Share the result and what happens next, including any extra training.
Check these first
Before changing anything, find out what is true today. Use your own records for a defined period and note gaps in the evidence. The review may take longer if records are incomplete or spread across teams.
- List hires from the last quarter and note how many weeks passed before each worked on live cells alone.
- Check whether each new hire has a sign-off sheet with dates.
- Ask two recent joiners what safety rule they were told first.
- Count early exits in the last six months and the reasons given.

Questions owners ask
Keep the safety day and the sign-off order fixed, but run them for groups. Pair each person with a trainer so output rises without skipping the basics.
Look at safety habits, quality of work and willingness to ask. A fast worker who ignores tool rules is a risk, however good the output.
Yes, but treat them as new. Habits from another plant may not match your rules, so run them through the same first week.
We set up the interview and hiring process for battery pack makers
Every business interviews, but few have a written process that works the same way for every role and every interviewer. GullyHR designs yours, from the role brief to the offer, trains your managers to run it, and can run it for you on the roles you hand us.
