Where to actually find good people
Job boards are last resort. The best hires come from places most owners don't think to look.
Your existing team is your first recruiter
A $500 to $1,000 referral bonus paid in two parts (half at hire, half at 90 days) outperforms most paid job ads. Your best employees know other good operators in the trade.
Trade school instructors and suppliers
Instructors know which students show up and which don't. Parts counter staff at your supplier hear who is unhappy at competing shops. Both networks are free and underused.
Indeed and Facebook are volume, not quality
Use them when you need to see a lot of resumes fast. Don't expect signal from the average applicant. Filter aggressively and assume 90% noise.
Take your version of this question further
This is one operator-tested angle on the question. Your shop, your size, your trade, and your team change the answer. Ask your specific version inside Ask a Shop Owner to get a response grounded in how owners like you actually handled it.
