#328 The Real Problem Isn’t the Lack of Skilled Labor—It’s Leadership.
The technician shortage isn’t just about a lack of interest or younger generations turning away from the trades. It’s about years of failed leadership, broken promises, and workplaces that left passion out in the cold.
This week on Wrench Nation we dig deep into one of the industry's most pressing crises—and we're not pulling punches.
We're joined by special guest Josh Parnell of Limitless Leadership , a voice that's challenging the status quo and calling out the cultural rot from the top down.
From toxic shop environments to outdated mindsets that value profit over people, Josh helps us unpack how bad leadership has driven good techs out of the bays—and how real, intentional leadership can bring them back.
If you've ever wondered why the tools are there but the hands are missing, you won’t want to miss this conversation.
