Diesel Techs: Tired of shops that talk a big game but can't back it up?
You've heard it all before:
"We're like a family here" — until you need a day off.
"We invest in our people" — but you haven't been to a training class in three years.
"Great pay and benefits" — that somehow never adds up to what they promised.
Your ideas for doing things better? They nod, smile, and nothing changes.
Sound familiar?
Here's the thing: the work isn't the problem. You like turning wrenches. You like solving problems. You like the satisfaction of handing keys back to a driver and knowing that truck is RIGHT.
What wears you down is everything around the work. The politics. The empty promises. The feeling that nobody running the place actually gives a damn about the people doing the hard stuff.
We get it. And we're not going to insult you with a bunch of corporate fluff.
J&R Service Center in Gardner, IL has been doing this since 1995 — 30 years of taking care of trucks, trailers, and the people who fix them. We're family-owned, and we run our shop like it. Not "family" as a buzzword. Family as in: the decision makers are on-site, the door is always open, and when you say something needs to change, it actually changes.
We're looking for a couple experienced diesel techs who are done with the B.S. and ready to work somewhere they can actually build a career.
Here's what makes us different — and we can prove every word of it.
✅ HERE'S WHAT WE PROMISE OUR TECHS:
✓ REAL MONEY — UP TO $135,000/YEAR — We offer transparent pay with a bonus structure that rewards performance. No guessing games. No bait and switch. When you produce, you earn — and we make sure you know exactly where you stand. Our diesel techs are among the highest-paid in the region because we believe skilled technicians are worth every dollar.
✓ WE SHUT THE SHOP DOWN EVERY MONDAY FOR TRAINING (AND YES, YOU GET PAID) — Read that again. Every single Monday, we close the doors to customer work and dedicate the day to training. You get paid your full rate to learn — not squeezed into some half-hour lunch session where you're barely paying attention. We bring in top-level instruction, and the whole team eats lunch together on us. Name another shop that puts their money where their mouth is like that. We'll wait.
✓ YOUR WEEKENDS ARE YOURS — PERIOD — Monday through Friday. No Saturdays. No "just this once." No on-call nonsense. Your kids' games, your projects, your life — they matter here. Paid holidays and paid vacation on top of that, because you need time to recharge and we're not going to pretend otherwise.
✓ AIR-CONDITIONED SHOP WITH REAL TOOLS — Not a sweatbox in August and a freezer in January. Our shop has AC, proper lighting, and the diagnostic tools and equipment you need to do the job right. Uniforms provided. We reinvest in the shop because a productive tech needs a productive environment — not a building that's falling apart around them.
✓ YOUR VOICE ACTUALLY MATTERS HERE (OPEN-DOOR POLICY) — The owners are on-site. Not in some office two states away. If you need something, you walk in and talk about it. If everything's good, we stay out of your way and let you work. That's it. No micromanaging. No corporate layers between you and the people who can actually make decisions.
✓ WE'LL KEEP YOU BUSY — We've built a solid reputation over 30 years, and our customers trust us with their medium and heavy-duty trucks, trailers, and fleet vehicles because we do the job right. That means steady work, not feast-or-famine cycles that leave you wondering if you'll have hours next week. Job security and consistent workflow so you can focus on the work, not stress about car count.
✓ CAREER GROWTH THAT'S REAL, NOT JUST A LINE IN AN AD — Want certifications? We'll help you get them. Want to develop leadership skills? Let's map that out. Want to master a new diagnostic system? That's what Monday training is for. Your goals matter here because when you grow, the whole shop gets stronger.
✓ NO DRAMA, NO POLITICS — We don't tolerate wrench-throwers, prima donnas, or people who poison the culture. Life's too short to work with toxic people, and we've been around long enough to know what kills a good shop. We shut it down fast so you never have to deal with it.
✓ YOU'LL WORK WITH PEOPLE WHO ACTUALLY HAVE YOUR BACK — This isn't a shop where you're on an island. Our techs help each other out, share knowledge, and work as an actual team — not a bunch of individuals fighting over the best jobs. When the shop wins, everybody wins.
✓ RELOCATION ASSISTANCE AVAILABLE — Not local? If you're the right fit, we'll help you make the move. Gardner is an affordable, low-key town with easy access to everything you need (more on that below).
✅ SEE WHAT OUR CUSTOMERS SAY ABOUT US
✓ 4.9-STAR RATING WITH 208+ REVIEWS — Our customers trust us because we do things right. That means you'll be working for a shop you can be proud of — not one that cuts corners or oversells work just to hit a number.

ABOUT GARDNER, IL
Gardner sits right on historic Route 66 in Grundy County — small-town living with big-city access when you need it.
- Affordable housing — Your paycheck goes further here than in the Chicago suburbs. Buy a house with a garage, not a closet-sized apartment for the same price.
- Joliet is a quick 30-minute drive — Shopping, dining, entertainment, Chicagoland Speedway, and the Joliet Slammers are all right there when you want them.
- Chicago is about 70 miles north — Close enough for a Bears game, a concert, or a weekend in the city. Far enough that you don't deal with the traffic, taxes, and headaches every day.
- Starved Rock State Park is less than an hour away — 18 canyons, waterfalls, hiking trails, and some of the best scenery in Illinois. Perfect for weekend family trips or just getting outside.
- Matthiessen State Park nearby — More trails, rock formations, and creek beds for when Starved Rock gets too crowded.
- Hunting, fishing, and outdoor recreation — Grundy County and the surrounding area offer solid deer hunting, bass fishing, and plenty of open space to ride ATVs or snowmobile in winter.
- Route 66 heritage — Gardner is home to the historic Two-Cell Jail and Streetcar Diner. There's a community feel here that the big suburbs lost a long time ago.
