First-Line Supervisors of Mechanics, Installers, and Repairers

617,500 US workers · median $79,860/yr · Trades

EXPOSED

The paperwork half of this job — work-order routing, shift scheduling, parts requisitions, warranty claims, PM compliance logs, productivity reports — is exactly what scheduling software plus LLMs now handle, and fleet/maintenance platforms are already absorbing it. The half that holds is standing in the bay or on the site: verifying a tech's diagnosis on a stubborn intermittent fault, deciding whether a unit is safe to release, handling a customer escalation, and being the name on the OSHA and comeback investigations. Modal worker here is a shop or field-service foreman who came up as a technician; the credential is experience, not a license, which limits the shield.

10-year outlook: By 2035 the clipboard-and-scheduling portion of the role is largely software-run and spans widen — fewer supervisors covering more techs — but the person who walks the bay, verifies the fix, and owns the safety call is still on payroll.

US employment, 2019–2025+27.1%
485,700617,500 workers

Headcount grew steadily across the period.

Median pay $67,460 → $79,860 -5.3% in real terms (nominal +18.4%, less ~25% US inflation over the period)

The job count is not the verdict

This line is counted by the Bureau of Labor Statistics — the one figure on this page that isn't a judgement of ours. Headcount moves on demand, offshoring, demographics and the business cycle, and automation is one term among several, often not the loudest.

So a falling line is not evidence that AI did it, and a rising one is not evidence that it won't. Both happen in this register: some occupations resist automation and shrink anyway, others are highly automatable and keep growing. The marked year is 2020.

BLS projection, 2024–2034

+3.1% 617,500 → 636,500 on the projections basis

Growing, and only partly exposed

The BLS expects +3.1% more of these jobs by 2034, and at 62/100 the work is only partly exposed — some tasks are automatable, the core of the job is not. Nothing here is in tension.

Different clocks. The score is what current AI could do to this work today. The projection is how many of these jobs will exist in 2034. Everything between the two — how fast employers actually adopt, whether demand grows in the meantime — is why they can point opposite ways without either being wrong.

~52,400 openings a year on average, including replacing people who leave.

Score — 62/100 resistance

Holding it up: judgment & accountability (16/20). Weakest point: liability shield (7/20).

Five dimensions, 0–20 each, summed. Higher means more protected. The arithmetic is shown so you can check it: 13 + 15 + 7 + 11 + 16 = 62. · Scored 2026-08-11, and re-examined when evidence accumulates rather than on a schedule.

Task resistance 13/20

Mixed — a routine tier and a judgment tier At 13 the split is roughly even: dispatch boards, PM interval tracking, warranty submission, tech productivity scorecards and parts reorder points are already running themselves inside CMMS and dealer DMS platforms, but nobody has automated walking out to a bay to confirm a tech misread a live-data freeze frame, road-testing a repair before it goes back to a customer, or deciding which of four jobs the one guy who can weld aluminum takes first — that's why it isn't 8, and the volume of screen work is why it isn't 17.

Embodiment 15/20

Hands-on in uncontrolled environments 15 reflects that the supervisor's day is spent in the shop or on the customer's roof, lift bay, boiler room or job site — lockout/tagout verification, torque and leak checks, confined-space and fall-protection sign-offs, riding out with a tech on a comeback — in environments with jacked-up vehicles, live refrigerant and energized panels rather than a controlled test cell, though the desk hours for scheduling and payroll keep it out of the high teens.

Liability shield 7/20

Certification preferred, not legally required 7 rather than 3 because many of these supervisors hold real tickets — EPA 608, ASE Master or L1, state HVAC/electrical journeyman or contractor licenses, DOT brake and annual-inspection certification — and in some jurisdictions the shop's inspection or contractor license runs through a named individual; it isn't 14 because the majority path to foreman is seniority and diagnostic skill, and when a repair fails the claim generally lands on the employer's garagekeeper's coverage, not on the supervisor personally.

Trust premium 11/20

Some relationship component 11 because the fleet manager, plant maintenance chief or property owner calls this specific foreman by name after the third failed repair and often keeps their business because of him, and the crew stays for the supervisor as much as the shop — but the work is largely institutional, jobs get routed by contract and location, and a competent replacement foreman keeps most accounts.

Judgment & accountability 16/20

Exists to be accountable for ambiguous calls 16 is earned by the release decision: signing off that a brake job, gas furnace, crane or aerial lift is safe to return to service, deciding whether an intermittent fault warrants tearing down further or sending it out, judging when a technician is unqualified or impaired for a task, and being the person interviewed when OSHA arrives after an injury or when a released unit fails in service — high-stakes calls made on incomplete diagnostic evidence, with procedures that guide but do not decide.

Where this experience transfers — nothing clears the bar

No occupation passed every test: close enough to first-line supervisors of mechanics, installers, and repairers on skills and subject matter, at least 10 points more resistant, no big jump in training, no new licence, no pay cut, and not shrinking on its own. That happens for 223 of the 654 occupations here that aren't SAFE, and it is worth stating plainly rather than leaving the section off.

The usual reason is that exposure travels with the skill profile. The jobs most similar to yours tend to be exposed for the same reasons yours is, so the near neighbours don't clear the gap — and the ones that do are a different kind of work, not a transfer of what you already know. Read that as a limit of this method, not a verdict that you're stuck: it only compares whole occupations, and it cannot see specialisation, industry, or anything you'd bring that isn't in a federal skill survey.

Here is that claim on your own job rather than in the abstract. These are the three occupations closest to this one by skill and subject matter — the places the work would most naturally transfer — with what the register scores them:

First-Line Supervisors of Production and Operating Workers EXPOSED 56/100 (-6) · 71% overlap
First-Line Supervisors of Construction Trades and Extraction Workers SAFE 73/100 (+11) · 68% overlap
Service Unit Operators, Oil and Gas EXPOSED 61/100 (-1) · 67% overlap

That is the whole problem in three lines. The nearest work is not meaningfully safer, so there is no move here that trades a similar skill set for a better verdict. This is not us running out of ideas — it is what the neighbourhood looks like.

What would move this occupation up is the other direction, and on this page it's the more useful one.

What would move this back up — beyond any one person

The moves above are yours to make. This is the other half: what would have to change in the world for the occupation itself to score higher. None of it is in any one person's gift, but it is where the floor actually comes from. Scores here are not a one-way ratchet. Only two of the five dimensions — task resistance and embodiment — track what machines can do. The other three track law, what buyers will pay for, and who is answerable, and those move in both directions, often in response to the same pressure AI creates. If every lever below landed, this occupation would score around 77/100 — SAFE.

5 specific changes that would raise this score
  • already happening liability shield +3

    OSHA 'competent person' and lockout/tagout designations becoming a documented, individually-named role in insurer-required safety programs, with workers' comp carriers and general liability underwriters conditioning premiums on a named human supervisor sign-off for confined space, energized work, and lift/crane operations — already appearing in construction OCIP requirements.

  • already happening judgment accountability +3

    As diagnostic AI and telematics take over routing and fault-code triage, the residual decision — release-to-service on an ambiguous intermittent fault, or pulling a unit from a revenue run — concentrates on the supervisor, and post-incident NTSB/OSHA/plaintiff discovery names that person. Task-mix shift, no new law needed.

  • plausible liability shield +4

    Expansion of named-competent-person / signatory requirements into more maintenance domains: FAA Part 145 already requires a certificated Repair Station supervisor and an RII (Required Inspection Item) inspector to sign; FTA/state DOT bus and rail maintenance rules and elevator/boiler inspection codes name a licensed supervisor. If a state adopts mandatory heavy-vehicle inspection programs (as several have debated post-CVSA out-of-service data) that require a named supervisor's signature on brake and steering releases, or if EPA 608/609 refrigerant recovery enforcement pushes to a supervisor countersignature, the shield rises for those subsectors.

  • plausible task resistance +3

    Two genuine tiers exist here. If maintenance platforms (Fleetio, UpKeep, ServiceTitan) absorb scheduling, warranty claims, and PM logs, the remaining job is verification-in-the-bay, tech coaching, and comeback root-cause — which raises task_resistance as a share of the job even as absolute headcount falls. Watch for shops where the foreman no longer touches the WO system at all.

  • plausible trust premium +2

    Narrow route only: in high-stakes independent shops and specialty/vintage/heavy equipment work, customers ask for a specific named foreman to inspect. This is real but small and does not scale to fleet or dealer-network work, where the buyer is a procurement department indifferent to who signed.

The limit. The binding constraint is that the credential is experience, not a license — absent a genuine journeyman-supervisor licensure regime (which no US state body is currently moving toward for general mechanical trades), the shield stays capped in the low teens. Realistic ceiling around 72-75, and the gains come from concentration of accountability onto fewer supervisors rather than from protecting the current 617,500 headcount.

These are conditions, not forecasts — what would have to happen, not what will. Specific rules, cases and bills are named so you can go and check whether they exist and where they stand; verify before relying on any of them. Nothing here is legal or financial advice.

Where this work is, and what it pays there

BLS metro figures for 392 areas. The verdict above does not change by city — the rubric judges what the work involves, not where it happens — but pay and headcount do, and the national median hides a very wide range.

Who is actually doing this — nobody, on the record

We have no reported case of a named organisation automating this occupation. Not one deployment, not one announcement.

That is worth saying out loud next to a score of 62. The verdict above is about what the work exposes — what current AI could do to these tasks. It is not a claim that anyone has done it. For this occupation those two things have come apart completely: the capability argument is on this page, and the evidence column is empty.

Read that as a gap in the reporting we can see, not proof of absence — the dispatch runs on English-language feeds and misses plenty. If you know of a case, tell us, or add a field report from inside the job.
