October is Employee Ownership Month, and at Franklin Building Supply, that's something worth celebrating!

Our Caldwell employee-owners came together for Crock-tober, an “anything in a crockpot” potluck featuring chili, dips, and plenty of other great food.

Events like this are a fun reminder of what makes employee ownership special: we're not just coworkers, we're owners building Franklin's future together. Sometimes, building that future involves a whole lot of crockpots!

Need nails, tools, or accessories on the jobsite fast? Call it into the store and our Nail Van will have it to you within two hours. Right to the jobsite, right to your truck.

Built for framers and siders who cannot afford to stop working, our Fastener Response Team runs out of Inside Sales so nothing slows down. We will even jump in on a Hot Shot run for the yard or door shop when a load cannot wait.

Keep an eye out for the wrap around the Treasure Valley. You cannot miss it.

Our reader board gets it.

Nobody told you adulting would feel like this. Good thing we have straight lumber and square corners -- some things in life actually line up.

Earlier this year, as part of our 50th anniversary, we made a commitment to give back to 50 families in the communities we call home.

This community is the reason we are still here after 50 years. It means everything to show up for it.

For our 50th year + our 10th year as an ESOP, we gave our location leaders one challenge:

Find one thing that could transform your breakroom into an Owners Lounge. No playbook. No script. Just -- what does your crew actually deserve?

What came back was better than we expected.

Some locations tackled the furniture -- real sectionals, tables that actually fit the whole crew, seating that respects the fact that these people have been on their feet all day. Some went for fresh paint, game rooms, and entertainment setups. Some built out locker areas that finally work. Some went all out -- full gyms. Squat racks, free weights, cardio equipment, the whole thing. At least two locations built gyms from the ground up.

Every single location did something. Not because they had to. Because we want spaces our employee owners are proud of. Swipe to see a few of our favorites.

"Camo and Elk Legs." That is the episode title and honestly it tells you everything you need to know.

Find it at aintthatsomethin.com or scan the code above. You are going to want to listen to this one.Season 2 is proudly sponsored by Trus Joist, a Weyerhaeuser company.

Our team is always leveling up!

Weyerhaeuser recently came in to train our team on Azek. When our people know the products inside and out, our customers get better answers, better recommendations, and better results on their projects.

That’s the FBS difference — people who know their stuff.
