No voice tool can promise to cut technician turnover, and any vendor that quotes a percentage should be asked where it came from. What a shop can do is look at why technicians actually leave and find the parts it controls. ATRI’s 2025 study of the diesel technician shortage linked six factors to techs looking elsewhere. Pay is one of the strongest, and software can’t touch it. But three of the six are about how people in the shop talk to each other, and in a multilingual truck shop, language sits right in the middle of them. This guide maps those factors, shows what one avoided departure is worth, and sets out how to measure whether voice work orders help.

Six reasons diesel technicians stay or go, and the three that language touches
Factors ATRI found significant in whether technicians look for other jobs. Pay is among the strongest, and is outside any tool’s reach. Relationships and mentorship are where a technician’s strongest language makes a difference.
Certification incentives
Language link: some
Variety of work
Language link: none
Interactions with management
Language link: strong
Interactions with colleagues
Language link: strong
Mentorship at the start
Language link: strong

16.5% a year: how fast truck shops are losing technicians
ATRI’s 2025 research found annual technician turnover of 16.5%, a vacancy rate near 20% and 65.5% of diesel shops understaffed, according to CCJ’s coverage. It also found 44% of trucking technicians were considering other technician jobs, most often in automotive and agriculture. For context, the Bureau of Labor Statistics reported a quits rate of 2.0% a month for transportation, warehousing and utilities in August 2026. Turnover is not a crisis in every shop, but in a shop that is already short, every departure means more overtime for the techs who stay.
Mapping ATRI’s retention factors to what language can and can’t change
Here is an honest look at each factor ATRI found significant. The aim is to be clear about where a voice tool has a real role, and where it has none.
| Retention factor | Does language affect it? | What voice work orders can do |
|---|
| Pay | No link No. Pay is set by the market and the shop. | Nothing. A voice tool doesn’t change what a technician earns. |
| Certification incentives | Partial Partly. Proving skill is harder when the record of your work is thin. | Complete work orders show which jobs a technician has done well, which supports certification-based pay steps. |
| Variety of work | No link No. Variety depends on the fleet and the jobs. | Nothing directly, though a visible history makes it easier to give a tech new types of work. |
| Interactions with management | Direct Yes. Misread notes and disputed defects become conflicts. | Structured tickets and a kept transcript settle what was actually said. |
| Interactions with colleagues | Direct Yes. Shift handovers fail when notes are vague. | The next tech picks up a half-finished job from a clear record, in fields everyone reads. |
| Mentorship at the start | Direct Yes. New techs learn faster in the language they think in. | A mentor can review spoken tickets with a new tech, in that tech’s language. |
Three direct links out of six is a modest claim, and that’s the point. A tool that improves how technicians, leads and the next shift understand each other works on the factors a shop controls, without pretending to replace a pay rise.
Mentorship is a day-one problem, before a new tech ever touches a trailer
ATRI asked technicians about the barriers they faced when starting out. Tool costs and a lack of technical knowledge led, but poor mentorship came up for more than one in ten. ATRI also found that 61.8% of technicians entered the career with no formal training, so the first weeks in the shop are where most of them learn the job.

For a new tech whose first language isn’t English, mentorship and technical knowledge are the same problem. They are learning slack adjusters, glad hands and twist locks while also translating every instruction. A mentor who can review spoken tickets with them, in their own language, turns a weekly struggle into a weekly lesson.
The first year, step by step, and where language support fits
Untrained new technicians can feel overwhelmed and leave within weeks. Most of the retention value of language support sits in the first months, not years later.
Week 1
Overwhelmed
Untrained new techs can leave within weeks. Give them the shop glossary and a mentor on day one.
Weeks 2–6
Learning the units
Brakes, lights and tires on tractors and trailers. Let them speak every ticket, so writing isn’t a second test.
Months 2–3
First solo jobs
Weekly ticket reviews with the lead, in the tech’s language, based on what they did.
Months 4–12
Earning a step
The work history shows which jobs they can be trusted with, and supports the next certification or pay step.
What one avoided departure is worth in a 20-technician shop
This is a worked example, not a forecast. It uses ATRI’s averages to show the scale of the cost a shop is trying to avoid, so you can replace them with your own numbers.
Illustrative example using ATRI 2025 averages
Replace with your shop’s figures
Technicians in the shop
20
Annual turnover at 16.5%
about 3.3 departures a year
Training an untrained replacement
about 357 hours and $8,211 in trainee wages each
Yearly replacement training at that rate
about 1,180 hours and $27,100
One fewer departure a year saves at least
357 training hours and $8,211, before overtime and downtime
The real cost is higher. It includes overtime for the techs who cover the gap, tractors and trailers waiting for a free bay, and preventive maintenance that slips when the shop is short.

Management and colleague relationships are built on shared, readable records
ATRI found that shops with strong relationships among technicians keep them longer, and that interactions with management were one of the factors tied to techs looking elsewhere. In a multilingual shop, many of the friction points in those relationships come back to the record of the work.
With management
The disputed defect on a trailer brake
A lead releases a trailer and it comes back with the same fault. The tech says they flagged it; the note says otherwise. With a structured ticket and the original transcript kept, the conversation is about the trailer, not about who is to blame.
With colleagues
The half-finished chassis job at shift change
A day-shift tech starts a brake job on an intermodal chassis and runs out of time. The night shift needs to know what was done, what was ordered and what’s left. A clear spoken record in fixed fields lets the job carry on without a phone call.
Both of these depend on complete fleet maintenance records that every technician can add to easily and every lead can read.
Certification and pay steps need proof, and proof needs complete work orders
Pay and incentives for certifications were among the factors ATRI found significant. Many fleets tie pay steps to certifications or to the jobs a technician has signed off. A tech who writes thin notes because English writing is slow has a weaker record of their own skill, whatever their actual ability. When a technician can describe every job fully, the work history becomes evidence: fifty brake jobs on tractors and trailers with no comebacks reads the same whatever language they were spoken in. That doesn’t raise anyone’s pay on its own. It makes the case for a step fairer and easier to make.
Four retention claims to question before you buy any shop software
Retention is an easy promise to make and a hard one to check. When a vendor ties a tool to lower turnover, these are the questions worth asking.
“Customers cut turnover by X%”
Over what period, compared with what, and did anything else change, such as pay or management?
“Saves every tech an hour a day”
Measured how, in which shops, and on what mix of tractor, trailer and chassis work?
“Works in any language”
Which languages were tested on shop-floor audio, and for which part of the workflow?
“Techs love it”
Can you speak to technicians who use it, in their own language, without a manager present?
How to measure whether voice work orders help retention in your shop
Annual turnover moves slowly and has many causes. Track the leading signs alongside it, and compare a pilot shop or bay with one that hasn’t changed.
90-day retention for new hires
The early leavers cost the most and are the most sensitive to onboarding.
Quits per year, by shop
Compare pilot and non-pilot shops over the same period.
Tickets with a stated cause
A direct measure of whether documentation got easier.
Handover rework
Jobs reopened because the next shift couldn’t follow the notes.
Mentor review hours
Time leads spend with new techs on tickets, not retyping them.
A short survey in each tech’s language
Ask about daily friction, management and colleagues every quarter.

Technician turnover and multilingual voice AI questions
Does multilingual voice AI reduce technician turnover?
There is no published study that measures it directly. The case is indirect: voice work orders in a technician’s strongest language address three of the factors ATRI linked to techs looking elsewhere: interactions with management, interactions with colleagues and early mentorship.
What is diesel technician turnover today?
ATRI’s 2025 research put annual technician turnover at 16.5%, with 65.5% of shops understaffed, as reported by CCJ.
What does one technician leaving cost?
ATRI estimated that bringing an untrained new tech up to speed takes about 357 training hours and $8,211 in trainee wages, before overtime and repair delays.
Can voice AI fix pay problems?
No. Pay dissatisfaction was one of the factors most strongly tied to techs looking elsewhere, and no software changes it. What records can do is support certification-based pay steps.
Which languages does FleetRabbit’s voice work order support?
FleetRabbit’s published voice pages don’t list languages. Test your technicians’ languages in a demo before planning a rollout.
How long before we’d see a retention effect?
Expect months. Track 90-day retention and ticket quality first, because they move faster than annual turnover.
Keep your technicians by fixing the friction you control
Clearer records, easier handovers and mentorship in the language each tech learns best.
