Staff turnover planning treats leavers as a number you can forecast instead of a surprise on Monday morning. Your payroll records already show how many people leave each quarter, from which roles and at what point in their service. That history is enough to predict next quarter's gaps and start hiring before the resignations arrive. This guide is for operations and warehouse managers who run permanent and regular crews.
The method below runs on your own payroll data, so you do not need an industry average. Keeping people longer is a separate job: the post on retaining skilled blue collar workers covers pay, training and recognition, and the post on retention incentives for seasonal staff looks at bonuses and non-cash perks for peak-season casuals.
Calculate turnover by role and by tenure band
Turnover rate is the number of people who left in a period divided by your average headcount in that period, multiplied by 100. This attrition rate calculation is simple, but one site-wide figure hides where the exits come from. The business.gov.au workforce planning guide includes staff turnover in its review of the current workforce and asks how often people leave and why. Answer that question in four steps:
- Pull the leavers list. Export everyone who left in the last four quarters, with role, start date, finish date and reason for leaving.
- Set tenure bands. Sort leavers by tenure at the finish date, in bands that suit your site, such as under 6 months, 6 to 24 months and over 24 months.
- Average the headcount. For each role and band, average the headcount at the start of each quarter.
- Divide. Leavers divided by average headcount, times 100.
Here is an illustration with made-up figures. A site averages 80 permanent staff and loses 18 in a year, which is 22.5 per cent. By tenure band, the under 6 months band lost 8 from an average of 16 (50 per cent), the 6 to 24 months band lost 6 from 24 (25 per cent) and the over 24 months band lost 4 from 40 (10 per cent). By role, packers lost 11 from 30 (about 37 per cent) and forklift operators 4 from 20 (20 per cent).
The site-wide 22.5 per cent hides the real pattern: the newest starters leave at five times the rate of long-serving staff, and packers drive the total. If your leaver reasons point to pay, the post on pay benchmarks for logistics roles compares logistics pay in Sydney and Melbourne.
Forecast next quarter's exits from your own history
A leaver forecast needs two inputs: the quarterly leave rate for each band and the headcount you expect in each band at the start of next quarter. With a year of data, divide each band's yearly rate by four. In the illustration that gives 12.5 per cent for the under 6 months band, 6.25 per cent for 6 to 24 months and 2.5 per cent for over 24 months.
Suppose next quarter starts with 20 people under 6 months, 22 in the middle band and 38 over 24 months, which is 80 in total. The forecast is 20 x 12.5 per cent = 2.5, 22 x 6.25 per cent = about 1.4, and 38 x 2.5 per cent = about 1.0. That is about five leavers, so plan for five. Run the same sums by role to see which jobs they are most likely to come from.
A forecast is an average, not a promise, so compare actual leavers with the forecast each quarter and adjust the rates. Retirements and critical-trade exits are better planned role by role, and the post on succession planning for tradespeople looks at them. The business.gov.au guide also asks you to pay close attention to roles that would be hard to replace, so flag those separately.
Turn the forecast into a hiring and training calendar
Work back from the date a leaver is likely to go. Your time to fill is the number of days from approving a vacancy to the replacement's first productive shift. Measure it from your last several hires in each role, and add the training lead time for induction, tickets and supervised shifts. The post on recruitment analytics in warehousing covers related measures, including time to hire, cost per hire and source of hire.
If packers take six weeks from approval to a productive shift (an illustrative figure) and the forecast says two packers will leave in the quarter, open those vacancies in the first week of the quarter, not when the resignations land. Then build the calendar:
- Hire ahead. For roles with forecast leavers every quarter, keep recruiting running so a resignation triggers a start date rather than a new search. Chandler Recruitment handles permanent recruitment for production and warehouse roles.
- Train ahead. business.gov.au notes that training an existing employee may cost less than hiring someone new.
- Give each action an owner and a date. The same guide says to decide who will do each action and by when.
Price a vacancy in lost output and overtime
The cost of staff turnover on a line is what the empty seat costs while it is empty. Two numbers capture most of it: the output you lose and the overtime you pay to cover. Count each hour of the vacancy once, in one bucket or the other.
An illustration with made-up figures: a packing seat stays empty for 20 working days of 8 hours, which is 160 seat-hours. Overtime covers 100 of those hours. The other 60 hours go uncovered, which is 7.5 shifts. If the seat packs 150 units a shift and each unit contributes $2 after materials, the lost output is 7.5 x 150 x $2 = $2,250.
The overtime cost is the extra you pay for those 100 hours: your own overtime cost per hour from payroll, less the ordinary pay you are not paying while the seat is empty. Wages you do not pay for the empty seat offset part of the cost, so net them off before you report a figure.
To price an hour of an employed worker, use the article on labour cost per hour for blue collar roles. Multiply the cost of one vacancy by the forecast leavers to see the quarter's exposure.
Plan cover for the gap between resignation and replacement
The gap runs from the leaver's last shift to the replacement's first productive one. Write a vacancy cover plan for each role before the seat empties, naming who covers, in what order and who approves.
- Cross-trained crew. A skills matrix shows who can cover which job, so the plan starts with people already on site.
- Changed hours or roles. Move hours or split a task so fewer jobs depend on the empty seat.
- Overtime for short gaps. Cap the hours and watch how many fall on the same people.
- Labour hire. business.gov.au lists contractors or temporary staff as an option for filling a gap.

Frequently Asked Questions
How do I calculate staff turnover for a production team?
Divide the number of people who left in a period by your average headcount in that period, then multiply by 100. Average the headcount at the start of each quarter. Do the sum again for each role and tenure band, because one site-wide rate hides where the exits come from.
What is a normal turnover rate for warehouse or factory workers?
It varies by site, role and tenure, so no single figure fits every team. A more useful benchmark is your own history. Calculate the rate for each role and tenure band over the last four quarters, then compare each new quarter against it to see whether a band is getting better or worse.
How far ahead should I start hiring to replace a leaver?
Work from your own time to fill. Measure the days from approving a vacancy to the replacement's first productive shift across your last several hires in that role, and add any ticket or training lead time. Then open the vacancy that many days before the expected leaving date.
What does an empty role really cost a production line?
Two main costs are lost output and overtime. Multiply uncovered shifts by output per shift and your margin per unit, and cost the overtime hours at the extra you pay over ordinary pay. Count each hour once. Recruitment cost and induction time are separate lines.
How can I cover a vacancy without overloading the rest of the crew?
Write a cover plan before the seat empties. Use cross-trained people first, change hours or split tasks, cap overtime and watch who carries it, and bring in labour hire or temporary staff for short-term or uncertain gaps. The plan should name who covers each shift.
Plan for leavers like you plan for orders
Staff turnover planning turns leavers into a forecast: calculate turnover by role and tenure band, apply the rates to next quarter's headcount, and start hiring against the result. Price one vacancy in lost output and overtime, and write the cover plan before the seat is empty. When you are ready to cover the gaps, you can request staff from Chandler Personnel.
