90 Day onboarding guide
Hiring and onboarding skilled tradespeople is not the same as hiring office staff. Trades roles are highly hands-on, safety-critical, and depend heavily on tacit knowledge, so sloppy hiring or a weak onboarding program quickly shows up as costly turnover, accidents, and lost productivity. Below is an actionable, in-depth blueprint you can use to attract, vet, onboard, and retain high-quality skilled labor — plus the research-backed reasons it matters.
Why this matters (short, evidence-backed case)
New hires who experience effective onboarding show much stronger commitment to their employer — BambooHR reports that effective onboarding can make employees feel up to 18× more committed, which translates into better retention and advocacy. BambooHR
Structured onboarding significantly improves retention: interactive/structured onboarding participants are far more likely to stay long-term (multiple sources put the increase in the tens of percentage points — e.g., 69% more likely to stay 3 years in some studies). Shortlister+1
Much turnover is preventable: analysis from Gallup shows a large share of turnover is avoidable when employers address workplace factors (engagement, fit, onboarding). Reducing early-stage churn has immediate ROI. Gallup.com
Bottom line: invest in onboarding and you keep the people you hire, reduce replacement costs, and keep your job sites safer and more productive.
Before you hire: design the hiring funnel for trades roles
Define the role precisely (competency map). List must-have technical skills (e.g., diesel electrical diag., hydraulic troubleshooting), certifications, tools used, and the core soft skills (attendance, communication, teamwork). For each competency note: how it will be tested (work sample, assessment, interview question).
Use realistic job previews. For skilled labor, nothing beats a site visit, short ride-along, or a video showing a typical shift and pay/benefits. Realistic previews reduce “surprise quits.”
Targeted sourcing. Post on trade schools, union job boards, Facebook groups for mechanics/operators, targeted ads to local communities, and partner with apprenticeships. Offer referral bonuses for current crew who recruit proven friends.
Screening that predicts on-the-job success. Combine:
Short skills test (bench task or timed troubleshooting scenario).
Structured behavioral interview focused on attendance, safety mindset, and teamwork.
Reference checks emphasizing past reliability and specific examples of problem solving.
Transparent compensation and advancement paths. Tradespeople value clarity on pay progression, overtime, and upskilling opportunities. Put clear pay bands and promotion/leadership pathways in the job posting and offer letter.
First 90 days: a structured onboarding program (the core)
An onboarding program for skilled labor should be multi-phase, documented, and hands-on. Here’s a practical program you can implement.
Day 0 → Preboarding
Send a welcome packet with start time, direction to site, PPE expectations, required paperwork, a short “what to expect first week” video, and a contact number for a buddy/supervisor.
Complete all HR/admin paperwork digitally before arrival (W-4, I-9 equivalent, direct deposit, benefits forms).
Day 1 → Orientation + safety baseline
On-site welcome: meet the crew and safety officer.
Job-site safety orientation: site rules, emergency procedures, PPE, lockout/tagout — this is non-negotiable.
Paper checklist and brief competency baseline (what they can do today vs what they need to learn).
Week 1 → Core skills & supervised work
Assign a mentor/skill-buddy (experienced tech) for at least 30–90 days. Mentorship is the single most practical element that accelerates tacit learning.
Deliver concise, role-specific training modules: equipment overview, common diagnostics, company processes (timesheets, parts ordering, reporting).
Small, supervised work assignments — gradually increase complexity.
Month 1 → competency checks & feedback loop
Conduct a 30-day check-in: evaluate technical skill, safety behavior, attendance, and cultural fit.
Create a Personal Development Plan (PDP) identifying 3 priorities and who will train them.
Months 2–3 → skills validation & pathway planning
Perform objective skills validation (practical test or observed job task) and document results.
Discuss progression steps (lead tech, trainer, foreman) and what’s required to get there.
Ongoing (post-90 days)
Quarterly development checks and a 1-year retention review.
Structured continuing education: certifications, refresher safety training, and paid time for training.
Training methods that actually work for trades
Apprenticeship / mentorship model: pairing with experienced techs accelerates learning more than classroom alone.
Micro-learning + job aids: short videos and one-page checklists for recurring tasks (oil changes, alignments).
Simulation & bench tasks: perform diagnosis in a controlled environment before troubleshooting live equipment.
Shadowing + debrief: after shadowing, require the new hire to explain the task back to the mentor — reinforces transfer of knowledge.
Safety, compliance, and culture — non-negotiables
Integrate safety training into onboarding, not as an add-on. Make near-miss reporting and stop-work empowerment part of day-one culture.
Establish clear expectations about hours, call-outs, and overtime; consistent enforcement reduces resentment.
Celebrate milestones (30/60/90 days) and publicly recognize strong safety or quality behaviors.
Measurement: how you know it’s working
Track a small number of high-impact metrics:
New-hire retention at 30, 90, and 365 days. (Aim to cut early departures by half within a year.)
Time to competence (number of supervised shifts until independent work).
Safety incidents per new hire (should trend down as onboarding improves).
Manager/mentor satisfaction with new-hire readiness.
Cost to replace (quantify hires lost early; recruiting + downtime + productivity loss).
Use exit interviews and 30/60/90 surveys to learn why people leave early and fix the most common causes quickly.
Common pitfalls to avoid
Treating onboarding as paperwork day only. (This is the single biggest mistake.)
Leaving new hires to “figure it out” on live jobs with no mentor — this increases mistakes and early turnover.
Failing to set clear expectations on attendance, pay, and advancement.
Not measuring outcomes — if you don’t track retention and time-to-competence, you’ll never prove ROI.
Expected ROI
Replacing a skilled trades employee can cost thousands — recruiting, training, lost billable hours, and safety risk. Research and industry analyses consistently show structured onboarding materially reduces early turnover and improves productivity; studies report large retention improvements (examples above show major multipliers in commitment and multi-year retention gains). Invest in structured onboarding and mentorship and you’ll see faster productivity, fewer mistakes, and lower replacement costs. BambooHR+2Devlin Peck+2
Quick implementation checklist (first 30 days)
Create competency map for each role.
Build a 90-day onboarding document with daily/weekly objectives.
Assign mentors and train them how to mentor.
Prepare preboarding materials and one-page job aids.
Set up metrics dashboard: 30/90/365 retention, time to competence, incidents.
Run pilot with next hire and collect structured feedback.
