The 90-day probationary period isn’t protecting you. It’s giving you permission to avoid a conversation you should’ve had at week three. Think about your last bad hire. Interviewed well. Said the right things. Showed up on time that first week. Then week two happened. Late on Monday. Long lunch on Wednesday. Asked your lead tech the same question for the third time. Your advisor gave you that look. The one where she doesn’t say anything, but you both know. So you started negotiating with yourself. “Maybe he needs more time.” “Maybe it’s the learning curve.” “Maybe I’m being too critical.” Week four. Week six. Week ten. Nothing changed. You knew at week three. Your lead tech knew at week two. That’s not patience. That’s avoidance. Here’s what that avoidance actually costs you. In a three-tech shop, one underperformer doesn’t just drag. It compromises everything around it. Comebacks. Bottlenecks. Cars that should take three hours taking six. Your good techs notice. They don’t say anything to you. They say it to each other. And they start thinking about who else is hiring. Meanwhile, you’re not running your shop. You’re babysitting a problem you identified two months ago. One shop owner I talked with handles this differently. She tells every new hire on day one: “We will all know within 30 days if this is going to work or not.” Not a threat. A mutual agreement. She calls it a mutual audition. You’re evaluating them. They’re evaluating you. Both sides know the timeline. Here’s what her first 30 days look like: Days 1–2: No wrenches. Systems only. Learn the software. Learn the workflow. Learn the board. This does two things — gives them a fair start, and shows you immediately how they absorb information. Days 3–10: Supervised work. They’re looking at cars. Doing DVIs. Writing up what they find. Your lead tech is watching — not hovering, watching. Do they ask questions when they’re stuck? Do they help the tech next to them? Do they show up on time?

What happened in the industry. What it means for your shop. What to do about it. 90 years. That's how long Grismer Tire & Auto Service has been family-owned in Ohio. Dayton. Columbus. Cincinnati. 28 locations. Three generations. Community roots so deep they practically hold up the sidewalks. Last week, Dallas-based private equity firm CenterOak Partners bought them. And that deal tells you more about where this industry is headed than anything else I've seen this year. But Grismer wasn't the only story. Sun Auto confirmed two separate acquisition clusters. A brand new PE firm announced it's entering the tire and auto space with $45 million and a single mission: build one platform from scratch. And the Driven Brands legal situation just got uglier. Here's what happened, what it means for your shop, and what to do about it this week. CENTEROAK BUYS GRISMER: THE DEATH OF "TOO LOCAL TO SELL" CenterOak Partners — a PE firm managing $2.5 billion in equity capital — completed a majority recapitalization of Grismer Tire & Auto Service on April 2nd. The family sold. The deal is done. Here's why this matters more than the average acquisition. Grismer wasn't some struggling chain looking for a lifeline. They were the gold standard. 90 years. 28 locations. An owner who was on the floor. The kind of shop that customers chose because they knew the people, not just the brand. And PE bought it anyway. CenterOak's track record tells you their playbook. They built FullSpeed Automotive to 600 locations and sold it. They grew CollisionRight six-fold and sold it. They built TruRoad into the second-largest auto glass platform in the country and sold it to Safelite. They didn't buy Grismer to keep it the way it is. They bought it to scale it. Expect tuck-in acquisitions in adjacent Ohio markets. Standardized service menus. Metrics-driven operations. And a corporate growth mandate that will inevitably change the feel of the place. Here's the part that matters to you: the "owner on the floor" culture that made Grismer special? That's now being traded for growth capital and a board of directors. And that means their most loyal "relationship-first" customers are going to start noticing.

Most shop owners interview technicians the same way every other employer does. Sit down. Ask questions. Shake hands. Hope for the best. Then three weeks later they're wondering why the guy who "nailed the interview" can't balance a tire without fumbling around like he's never seen a wheel weight. You've heard me call it "all hat, no cattle." (hat tip to my Texas friends!) They talk a great game. They've practiced their answers. They might even sound like they wrote the ASE study guide. But talking about fixing cars and actually fixing cars are two very different things. That's why the best shops I know don't just interview. They invite candidates to work. And the ones who do it well make it feel like the easiest, most natural thing in the world. No pressure. No weird tests. Just one simple line: 👉"If you ever want to see what a day feels like here, we'll pay you for your time." That one sentence does three things at once. It shows respect. It removes risk. And it tells the technician everything they need to know about who you are as a shop owner. The shops that run even a one-day working interview? They hire faster. They hire better. And they almost completely eliminate the "bad hire" that looked great on paper. The ones who do a three-day working interview? Phenomenal results. Almost zero regrets. You get to see if they show up on time. Come back from lunch on time. Whether they actually know their way around a bay — or just know their way around an interview. Stop hoping your gut feeling is right. Let the work speak for itself. By-the-way... This works for techs on your bench too. Have you been keeping in touch with a tech for a year or two with no forward momentum? Shoot them a quick text with that simple sentence and see what happens. Here it is again so you don't forget: 👉"If you ever want to see what a day feels like here, we'll pay you for your time."

One of our community members just got featured in a major industry piece. @Joe Marconi — shop owner for 40+ years — was asked what it actually takes to survive the next era of auto repair. His answer wasn't about EVs. It wasn't about equipment. It was about this: "Take care of your employees. Take care of your customers. They are the lifeblood to your legacy." Simple. But most shops are still getting it wrong. The full article covers where the industry came from, what's killing it now, and what the guys who built their careers the right way are saying about where it's headed. It's worth 9 minutes of your time. 🔗 [Industry Evolution: Insights from Retired Shop Owners on the Past, Present, and Future of Auto Repair]

A customer walks into a doctor's office. Waits 40 minutes. Sees the doctor for maybe 10. Walks out with a bill somewhere between $150 and $300 — sometimes more once the lab work hits. Nobody argues. Nobody Googles "is my doctor ripping me off?" Nobody storms out saying "I'm not paying that. All you did was look at me." Now picture the same person pulling into your shop. You spend 90 minutes running pinpoint tests on a complex electrical issue. Your tech uses $10,000+ in diagnostic equipment, cross-references technical service bulletins, checks wiring, sensors, connectors, and the ECM. You call the customer. "$125 for the diagnostic." Dead silence. "$125? Just to tell me what's wrong? Can't you just plug it in?" You've felt this. Every shop owner has. And here's what nobody talks about: the reason customers push back on your diagnostic fee has almost nothing to do with the fee itself. It's a double standard — and it runs deep. Let me walk you through exactly why this happens. Not in a theoretical way. In a way that'll change how you position your shop. The first problem is the white coat. Doctors are classified as "white collar." They think for a living. Mechanics are classified as "blue collar." They use their hands. That's not just a label. It's a cultural hierarchy baked into how people assign economic value to work. Thinking = expensive. Hands = cheap. Except your diagnostic tech IS thinking. That's the entire point of diagnostics. There are nearly a million technicians in the U.S. Only about 250,000 hold any ASE certification at all — and the fraction who reach Master status is even smaller. ASE offers 52 specialty certification tests. A Master Tech has to pass 8 of them, maintain years of on-the-job training, and recertify every 5 years. Meanwhile, over a million doctors hold board certification. And everyone knows what that means. Your techs went through a gauntlet too. The public just doesn't have a name for it. And part of the reason? We haven't given them one. More on that in a minute.
