The diesel technician shortage is a persistent and growing problem. The American Transportation Research Institute (ATRI)’s Technician Shortage report states that a majority of shops (65.5%) reported that their locations were understaffed in 2025, with an average vacancy rate of 19.3%. This isn’t just a number; it’s a daily struggle that impacts uptime, maintenance costs, and operational stability. Compounding the issue is an annual turnover rate of 16.5%, with understaffed shops experiencing a higher rate of 18.1% compared to fully staffed shops’ 7.8%, meaning the cycle of hiring, training, and losing talent never seems to end.

In response, many fleets have focused on increasing pay, but as the data shows, that’s not the whole story. The report indicates that the shortage is also caused by issues with training, recruitment, and retention that go well beyond just compensation or company size. The reality is that modern technicians are looking for more than just a paycheck; they’re searching for a fulfilling career where they can apply their skills to meaningful work. The smartest fleets are beginning to realize that the key to winning the talent war lies not just in offering a competitive wage but in creating a proactive culture that prioritizes their team’s professional growth and job satisfaction.

What Techs Really Want (and Why They’re Leaving)

To understand how to attract and retain technicians, you must first understand what drives them to leave. The ATRI report offers some insight: nearly 44% of trucking techs surveyed were considering alternative employment.

• The Firefighting Trap: Technicians ranked “more interesting work” and “variety of work” as top motivators for choosing a job. Conversely, a lack of variety was a top motivator for techs considering other jobs. When a technician’s day is filled with a constant stream of low-value, repetitive “firefighting” from unexpected breakdowns, it’s easy for the work to lose its appeal.
• The Burdens of Training: New hires, especially those without formal training, require an average of 357 hours of employer-sponsored training just to get up to speed. This investment of time and money is a significant burden for a short-staffed team. What’s more, the report shows that even formally trained technicians often feel unprepared, with over 30% reporting they were unqualified in core skill areas when they started their careers. This lack of qualification is also related to one of the biggest challenges cited by training programs: that many aspiring techs struggle with basic math and reading skills. The lack of confidence and hands-on knowledge in areas like electronic systems and diagnostics can make their first few months on the job feel overwhelming. In fact, according to WrenchWay, only 28 percent of techs thought that their shop did a good job of teaching new techs, and 48 percent of techs thought that their shop did not do a good job
• The Power of a Positive Culture: The report found that a lack of mentorship and poor shop training were significant barriers to a new technician’s career. On the flip side, strong relationships with colleagues ranked as a top source of job satisfaction for technicians already in the industry. Apprenticeship programs, in particular, are an effective retention tool, as techs who complete them have a turnover rate of only 6.9%, which is 58.2% lower than the overall average. This shows that a supportive, well-managed environment is a powerful, yet often overlooked, retention tool.

Creating a Proactive Maintenance Culture

So, how can fleets use this information to their advantage? The answer lies in a fundamental shift from a reactive “break-fix” model to a proactive “predict-and-prevent” model. This change empowers technicians, reduces the daily grind, and shows a commitment to an efficient, forward-thinking future.

The right technology is not a replacement for skilled labor; it is an enabler. Tech can take the burden of mundane tasks off your team while providing the data and intelligence needed to solve more complex problems.

A strong solution should:

• Automate the Mundane: Automate routine checks and maintenance-related tasks to free up technician time for more complex, engaging projects.
• Provide Actionable Intelligence: Translate complex data into simple, prioritized insights that enable your team to get ahead of problems before they become catastrophic.
• Foster a Positive Work Environment: Help streamline workflows and reduce the stress of unexpected, high-stakes repairs, thereby cultivating a more positive and productive shop culture.

Approaching your maintenance team this way demonstrates a commitment to their professional development, creating an environment where technicians feel valued, challenged, and empowered to excel.
