Plants are logging fewer breakdowns than five years ago, but each one costs more, and the people needed to get equipment running again are getting harder to find. New survey data shows the gap is already showing up as downtime, contractor spend and lost service revenue.
Most plants are breaking down less often than they used to. The problem is that every breakdown now costs more, and the one resource that decides how long a line stays down, a qualified technician with the right knowledge on the right shift, is getting scarcer every quarter. New survey data from maintenance leaders and equipment dealers published this month points to the same conclusion from both sides of the machine: the skilled labour shortage has stopped being a recruiting headache that HR can absorb. It is now showing up directly as downtime, contractor invoices and service revenue that never gets booked.
The cost side of the equation has been well documented. Siemens' True Cost of Downtime 2024 analysis estimates that the 500 biggest companies in the world lose approximately $1.4 trillion a year to unplanned downtime, equivalent to 11% of their total revenues. In automotive, a single idle production line in a major plant can cost up to $2.3 million an hour.
The same analysis shows why this is easy to miss. Plants now average 25 downtime incidents a month, down from 42 in 2019, and the average large plant loses 27 hours a month to unplanned stoppages, down from 39. Condition monitoring and predictive maintenance are doing their job on frequency. What they cannot do is fix the equipment once it has stopped. When failures are rarer but more expensive, the speed of the response matters more than ever, and response speed is a function of people as much as technology.
That is where the latest workforce data becomes an operations issue rather than an HR one. In a MaintainX survey of 211 maintenance and operations leaders, reported by Stacker on September 9, more than 70% said their teams had been understaffed at least some of the time in the past 12 months, and 37% described themselves as chronically understaffed, meaning often or almost always shorthanded.
The most telling number is the one that rules out the obvious fix. Sixty-seven percent of those leaders said their staffing shortages had nothing to do with budget or approval for additional headcount. Fifty-five percent named finding qualified candidates as the primary challenge. The money to hire exists; the people do not, at least not quickly. Seventy-two percent of roles take 60 days or more to fill, and 42% of new hires need more than three months to reach full productivity.
The consequences are exactly what an operations leader would predict. Among chronically understaffed teams, 46% say unplanned downtime is increasing because they are shorthanded. Forty-three percent of teams are working more overtime, which drives up maintenance costs and, in turn, turnover. And 48% of facilities now rely on contractors to fill the gaps, which the survey notes raises spend while slowing response times. A vacancy on the maintenance team does not stay a vacancy; it becomes longer repairs, tired technicians and an outside crew who has never seen the equipment before.
Many plants treat the OEM or the equipment dealer as the backstop when in-house capacity runs out. The dealer data suggests that backstop is under the same strain. The AED Foundation's 2026 Technician Shortage Research Report, released this month, estimates that agriculture and construction equipment dealers face a shortfall of approximately 10,000 diesel technicians every year, costing an estimated $7 billion annually in lost shop and parts revenue. A decade ago, the Foundation's 2016 study put that figure at roughly $2.4 billion.
The operational picture behind the number is stark. Seventy-seven percent of dealers say the shortage is hindering business growth, 72% report increased costs and operational inefficiencies, and 80% say they are unable to meet customer demand because they lack qualified technicians. North of the border the pattern repeats: the companion Canadian study, reported by Equipment Dealer Magazine, found that 78% of Canadian dealers cannot keep pace with customer demand, 25% have had technician positions vacant for more than 150 days, and 72% plan to raise technician pay this year.
For an equipment owner, that $7 billion is not an abstraction. Every hour of shop capacity a dealer cannot staff is a repair that waits, a part that sits on a shelf uninstalled, or a service call that slips to next week. The aftermarket revenue a dealer loses is, on the other side of the transaction, uptime the customer loses.
None of this argues for more job advertisements. The survey data is clear that hiring alone is not closing the gap fast enough. It argues for managing technician capacity as a constraint on uptime, with the same rigour plants already apply to critical spare parts.
The plants that treat the technician shortage as a hiring problem will keep posting vacancies and waiting. The ones that treat it as an uptime problem will start measuring it, designing around it and protecting the capacity they already have.
