Flat rate made sense at one time – is it still a viable pay structure for today’s highly sophisticated shop?
Flat rate is a controversial topic – but not a new topic. It is a system that is almost 100 years old, and at one time made sense for drivers, technicians and shops. It was born out of a need to standardize repair costs at new-car dealers.
When cars and trucks first hit the road, repair shops charged by the hour, as construction contractors do today. If a job took 3 hours, the customer paid 3 hours. Customers constantly accused shops of padding hours. Shops accused customers of trying to negotiate every bill. The system lacked consistency, trust and predictability. But, in defense of shops, cars of that era were bespoke machines produced in small numbers and owned by the upper classes.
As Ford, GM, Chrysler and others grew with vehicles for every purse and purpose, they needed their dealers to standardize repair costs. That’s when factory labor time guides began to show up in the 1920s. These early books were crude, often based on ideal shop conditions. This is the progenitor of flat rate. But some shops of the day didn’t pay technicians on a flat rate, according to old issues of Brake & Front End and Tire Review; they were paid by the hour on the job.
By mid-century, dealerships started tying mechanic pay directly to those time guides. If the job paid 1.5 hours, the tech got paid 1.5 hours. This system protected customers from endless bill inflation and incentivized speed and efficiency. Flat rate would quickly become the dominant pay method in dealership environments, especially as vehicle complexity grew after WWII.
In the 1960s, we saw the rise of independent labor guides covering multiple makes; some publishers of these books provided more realistic labor times. It worked for that era because there were fewer automakers and very similar vehicle designs. The exotic technology of those days was confined to the flagship models like Corvettes, Thunderbirds and Imperials.
By the 1970s, vehicles began to change due to emissions, platform downsizing and new regulations. This is when more imports from Germany and Japan started to hit the roads. The concept of diagnostic labor charges began to take hold as drivability diagnostics were required to service solid-state ignition and primitive fuel-injection systems.
This was also the age when technicians and engineers started to lock horns. It might have been the blocked spark plugs on a Chevy Monza V8 or a mess of vacuum lines under the hood.
But up until the 1990s, technicians on flat rate could make a decent living. But it was a time when more tools were required to service a greater variety of vehicles. But, technicians needed these tools to stay efficient to bill more hours.
Today, most technicians are paid flat rate. But, as mechanics transitioned to technicians, the labor databases and shops have not really evolved. This has resulted in more comebacks, corner-cutting, burnout and inconsistent income.
Why are we still using flat rate? Is it a benefit to vehicle owners? No. Is it a benefit to technicians? No. Is it a benefit to shops? No. While standardized labor times helped build trust in the automotive repair industry in the 1920s, they are like an anchor around our necks in the 2020s as we deal with more complex vehicles.
I am fine with labor time being used to ensure a consistent price for consumers. Still, as a way to compensate technicians, it is hurting our ability to attract new technicians and it’s burning out older technicians.
