Timelines, regional windows, and screening tactics backed by current BLS and ABC data. [![Paul Jones](/_next/image?url=https%3A%2F%2Fassets.basehub.com%2Fe0b5701f%2F6599306507912123f90f150a8bfaaf6c%2Fscreenshot-2026-01-28-at-10.53.16-am.png%3Fwidth%3D100%26height%3D100%26quality%3D100&w=96&q=75) Paul JonesHead of Growth at Classet ](/blog/authors/paul-jones) June 25, 2026 AI Recruiting, Skilled Trades _Last Updated: August 17, 2026_ Most contractors treat September as the start of the wind-down. Federal payroll counts disagree. Construction employment barely moves in September and October, then falls off a cliff from November through February. Seasonal hiring plans break in that gap between what the calendar feels like and what the payrolls do, because the crew decisions you make in September set what your February ramp costs you. **TLDR:** - Construction employment holds near its summer peak through October. Between October 2025 and February 2026 the industry shed 414,000 jobs, versus just 75,000 between July and September. - The labor market got tighter even as the work got softer. Construction backlog fell to 8.0 months in July 2026, the lowest since January, while job openings rose 36% year over year and construction unemployment sat at 3.7%. - Associated Builders and Contractors puts the 2026 need at 349,000 net new workers, rising to 456,000 in 2027. - September is the decision month: who you keep through winter, who converts to year-round, and who you pre-screen now for a February or March start. - AI phone screening contacts applicants within seconds and runs 24/7, which matters more in fall when you get fewer applicants per opening and cannot afford to lose any of them to a slow callback. ## What Construction Employment Does in the Fall Contractors plan around a mental model of the season that does not match the payrolls. Below is the not-seasonally-adjusted construction employment series from the [Bureau of Labor Statistics](https://www.bls.gov/iag/tgs/iag23.htm), the version that shows real seasonal movement instead of smoothing it away: - July 2025 peak: 8,476,000 - September 2025: 8,401,000 - October 2025: 8,413,000 - November 2025: 8,344,000 - December 2025: 8,199,000 - January 2026: 8,003,000 - February 2026 trough: 7,999,000 The industry gave back 75,000 jobs between the July peak and September, and October came in higher than September. The contraction runs from November through February, when 414,000 jobs came off the books. Peak to trough across the full cycle is roughly 477,000 workers, close to half a million people moving out of construction payrolls and back in every year. September is the last month when you still have full crews on site, a clear view of who performed, and runway to act on it. By December the people you wanted to keep have taken something else. ## The 2026 Twist: Softer Work, Tighter Labor Before you set headcount this fall, look at what happened to demand and labor separately. Demand cooled. Labor did not. ABC's Construction Backlog Indicator [fell to 8.0 months in July 2026](https://www.bdcnetwork.com/building-team/contractors/article/55397212/the-average-us-contractor-has-eight-months-worth-of-construction-work-in-the-pipeline-as-of-july-2026), down 0.8 months from both the prior month and a year earlier, and the lowest reading since January. Every industry, region, and company size saw backlog decline, with the South the only region still above where it was a year ago. ABC chief economist Anirban Basu noted that backlog in the $30 to $50 million revenue category fell to its lowest level since March 2020. Meanwhile, construction job openings [rose to more than 300,000 in June 2026](https://abcnews4.com/news/nation-world/construction-job-openings-rise-as-overall-job-openings-soften-june-2026-jolts-report-associated-builders-and-contractors), up 14,000 for the month and up 36% year over year. Construction unemployment was 3.7% in July while the all-industry rate was 4.1%. The industry added 22,000 jobs in July, with nonresidential specialty trades gaining 15,400 of them. A softer market for the work has not produced a looser market for the workers. Basu attributes the rising openings to a structural shortfall of skilled labor, experienced workers retiring, and undocumented workers leaving jobsites. Your backlog dipping does nothing to reverse any of the three. That should change how you read a fall headcount decision. When backlog falls, the instinct is to cut deep and rehire in spring, but at 3.7% unemployment and 300,000 open roles you will pay more to rehire than you saved by cutting. The 12% of ABC contractors under contract on a data center carried 11.4 months of backlog against 7.5 months for everyone else. Competing for electricians against [data center work](/blog/data-center-trades-shortage) means competing against firms with nearly four extra months of visibility, which lets them commit to a hire you are still modeling. ## The Workforce Math Behind the Squeeze Associated Builders and Contractors estimates the industry needs to attract [349,000 net new workers in 2026](https://www.abc.org/News-Media/News-Releases/abc-construction-industry-must-attract-349000-workers-in-2026-despite-macroeconomic-headwinds) on top of normal hiring, climbing to 456,000 in 2027 as spending growth resumes. Their model puts roughly 3,450 jobs behind every additional $1 billion in construction spending. The demographics underneath that are the part nobody can hire their way out of quickly. CPWR's research on aging in construction found the average worker age rose from 41.6 to 42.1 between 2011 and 2023, while the share of workers 55 or older climbed from 16.9% to 21.3%, a 26% increase. About one in five electricians is now over 55. Only 26.4% of wage-and-salary construction workers participate in a retirement plan, compared with 34.3% of workers overall, which makes retirement timing less predictable than a pension-heavy workforce would be. Turnover sits on top of all of that. Contractors are hiring to grow and hiring to stay even at the same time, which is why the volume of candidates a mid-sized contractor screens each year is far larger than net headcount change suggests. ## September Is the Decision Month Two calls land on your desk in September, and both get more expensive the longer you sit on them. The first is who you carry through the winter trough. Keeping a good foreman on the books through a slow January costs less than recruiting a replacement in March against spring wage pressure, and the replacement market is tighter right now than your backlog would suggest. The same record tells you who is ready to move to year-round work. Seasonal workers who held up across a full peak season make the cheapest reliable crew leads you will find, and in September your supervisors can still tell you which ones those are. The second call is who you screen now for a spring start. Most contractors kick off the [spring hiring push](/blog/construction-spring-hiring-surge-pipeline) in March, alongside every competitor in their market. Screen in the fall instead, when there are fewer applicants per opening but far less competition for their attention, and February opens with a warm list rather than a blank one. ## Building the Returner Pipeline Before the Season Ends Returning seasonal workers arrive already knowing your safety protocols, site culture, and crew dynamics, so they cost far less to onboard than new hires. The window to lock them in is while they are still on your jobsite. - Document performance now, while supervisors remember specifics. A written record of who showed up, who worked well under schedule pressure, and who handled a crew makes rehire decisions faster and less subjective in February. - Give people a concrete reason to commit early, whether that is a guaranteed start date, a modest return bonus, or first pick of the better assignments next season. - Run a real end-of-season conversation instead of a form. Ask who wants to come back, what would make them come back, and who is ready for a year-round or supervisory role. - Stay in contact through the off-season with brief periodic outreach, so you are already in mind when other contractors start posting in March. - Track which sites and supervisors produced the highest return rates. That tells you something about working conditions that no exit survey will. [Returners who move into year-round roles](/blog/skilled-craftsmen-recruiting-strategies) tend to make the most reliable crew leads, because they have seen both the peak crunch and the slow shoulder months. ## Working Backward From Your Spring Ramp Most contractors start recruiting about two weeks before they need crews on site. Count backward from the first day on site instead. ![Construction project timeline working backward from job site start date, showing onboarding, background checks, and sourcing phases](https://d4bkhhmrfehmf.cloudfront.net/media/46c5fb95-2bc3-485e-94d2-7604fb1bce97/c2t_AXbB7bRKAi8od14wn.png) - [Onboarding and safety orientation](/blog/ai-recruiting-setup-time) runs one to two weeks before a worker is productive on site. - Background checks and drug screening add three to five business days in most states, longer for federal sites. - Sourcing and screening enough candidates to make quality hires takes two to four weeks once you account for no-shows, drop-off, and scheduling back-and-forth. That puts your realistic start six to eight weeks ahead of your target crew date. For a March ramp in northern markets, the pipeline needs to be running in January. For anyone planning against the February trough, that means the groundwork happens this fall. ## Fewer Applicants Per Opening Makes Speed Matter More A slow callback in July costs you one candidate out of many. The same slow callback in November, with fewer people looking for work, can cost you the only qualified applicant you see that week. When a laborer or framer submits an application at 7 PM after finishing a job site, they are applying to several contractors in the same sitting. Whoever calls back first gets the interview. With construction unemployment at 3.7% and openings up 36% year over year, a 24-hour callback window is long enough to lose someone. ![Construction recruiting funnel showing many job applications flowing in at the top narrowing to an overwhelmed recruiter, illustrating the screening bottleneck problem](https://d4bkhhmrfehmf.cloudfront.net/media/46c5fb95-2bc3-485e-94d2-7604fb1bce97/UzgSociv0DT5r1bgEIeMU.png) Most contractors assume the problem is sourcing. Usually it is the screening layer, where a recruiter is calling each applicant by hand, playing phone tag for days, and still losing people to a firm that called first. - Every hour a qualified applicant sits uncontacted is an hour they spend talking to someone else. - A single recruiter carrying 30 open roles cannot reach every new applicant the same day, no matter how organized they are. - Candidates for hourly construction roles routinely apply to four or five employers at once, so first contact is often the deciding factor rather than pay rate. This is the same [capacity problem high-volume employers hit](/blog/high-volume-hiring-software) in any season. Fall just raises the cost of each miss. ## Regional and Weather Windows Heading Into Winter Where your crews work changes when these decisions land. Region Fall Position Next Hiring Window Planning Note Northern States Peak work through October, sharp drawdown November onward Late January through March Lock returners in September; the thaw ramp is won before it starts Sun Belt (Texas, Arizona, Florida) Productivity improves as summer heat breaks Rolling, with a fall and winter build Autumn is a working season here, not a wind-down Coastal and Hurricane-Prone Regions Storm-driven demand spikes through fall Event-driven, unpredictable Keep a pre-screened pool warm rather than sourcing cold after each event High-Altitude and Mountain Markets Season closes early, often by October February through April A four-to-six-month season means every week of hiring delay costs real throughput Northern and mountain markets get the hard version, because a compressed season means you staff the spring ramp from a standing start. Sun Belt contractors trade that for near year-round building, where competitors never stop recruiting either. ## How AI Phone Screening Fits the Fall Pipeline [Joy, Classet's AI recruiter](/features/ai-recruiting-agent), calls candidates within seconds of application and runs structured interviews around the clock. That covers two problems at once in the fall: it catches the applicants you cannot afford to lose while volume per opening is thin, and it screens a spring pipeline through November and December without pulling recruiters off current requisitions. - Joy contacts applicants within seconds rather than the next business day, which decides outcomes when skilled workers are fielding several conversations at once. - Structured summaries capture trade certifications, availability, and relevant experience, so recruiters spend their time on fit rather than fact-gathering. - Screening runs in 25+ languages, which matters on bilingual crews where an English-only process filters out qualified people without anyone noticing. - Around-the-clock coverage means someone who applies at 9 PM on a Friday is engaged before the weekend, [keeping the pipeline moving](/land/skilled-trades) through the slow months. ## FAQ Is September too late to hire for construction? No. Construction employment holds near its summer peak through October in the BLS data, so there is still work to staff. September is also the last month with full crews on site, which makes it the best month to decide who you keep through winter and who converts to a year-round role. The contraction people associate with fall runs November through February. When does construction employment actually drop off? November through February. Not-seasonally-adjusted BLS figures show 8,413,000 construction jobs in October 2025 falling to 7,999,000 by February 2026, a loss of 414,000. By comparison, the July-to-September decline was 75,000. Peak-to-trough across the cycle is roughly 477,000 workers. Should contractors cut crews this fall given that backlog fell? Cut carefully. ABC's Construction Backlog Indicator dropped to 8.0 months in July 2026, its lowest since January, so the caution is understandable. But construction job openings rose 36% year over year and construction unemployment was 3.7% in July, meaning the workers you release will be harder to replace in spring than the softer backlog suggests. The rehire cost often exceeds the winter carrying cost for proven people. How early should contractors start hiring for a spring ramp? Six to eight weeks before your target crew date. Budget one to two weeks for onboarding and safety orientation, three to five business days for background checks and drug screening, and two to four weeks to source and screen enough candidates after no-shows and scheduling delays. For a March start, that means the pipeline is running in January, and the groundwork happens in the fall. How many workers does the construction industry need? Associated Builders and Contractors estimates 349,000 net new workers in 2026, rising to 456,000 in 2027 as construction spending growth resumes. Their model attributes roughly 3,450 jobs to every additional $1 billion in construction spending. The aging workforce compounds it: CPWR found the share of construction workers 55 or older rose from 16.9% to 21.3% between 2011 and 2023. Can you build a pre-screened pipeline from past applicants instead of starting cold each season? Yes, and fall is the right time to do it. AI phone screening can re-engage candidates from previous application cycles the moment a matching role opens, using the same instant phone interview new applicants get. That turns last season's applicant pool and silver-medalist candidates into a list you activate in February rather than sourcing from scratch in March. How do you screen for OSHA, EPA, or state license requirements through an AI phone interview? Joy asks candidates about their credentials during the screen and captures the answers in structured summaries that sync to your ATS. For roles requiring [OSHA 10 or 30](/blog/osha-certifications-construction-workers), EPA lead certification, or a state contractor license, you configure those as qualifying questions so your team only reviews candidates who hold what your sites require. Can AI phone screening handle bilingual crews where Spanish is the primary language? Yes. Joy screens in 25+ languages, so Spanish-speaking candidates have a normal conversation in their preferred language instead of working through an English-only process. That raises completion rates and produces better screening data on roles where bilingual capability matters on site. Do construction candidates actually finish AI phone screens? Phone-based AI screening runs 60-70% completion across construction and trades roles, and 88% of Classet candidates complete their screen within 20 minutes of applying. The immediate response is the draw. Candidates would rather interview right now than wait days for a callback. What is the difference between AI scheduling tools and AI screening tools? Scheduling tools coordinate interview times, but a human recruiter still runs the actual screen, so your team is still working through every applicant. AI screening tools conduct the qualification interview themselves and hand back summaries, so recruiters review candidates who have already been vetted rather than chasing callbacks. Can you run AI phone screens without replacing your existing ATS? Yes. ATS Sync connects to your existing ATS and writes interview recordings, transcripts, and summaries directly into candidate profiles without workflow changes or a system swap. Integration typically takes two to three weeks for mid-market and enterprise teams. What happens when a candidate applies at 9 PM and your office is closed? Joy reaches them within seconds by phone and SMS and runs the structured interview immediately, so they engage while still interested instead of waiting for the next business day. This addresses the 64% of candidates who apply outside standard business hours, when no recruiter is available. ## What to Do With September Contractors lose the next season by treating September as an ending. It is the last month that gives you all three of the things a good crew decision needs: people still on site, performance you can evaluate, and enough runway to act before the November drop. This year sharpens it. Backlog softened while the labor shortage held, so whoever cuts hardest this fall pays the most in spring. Joy contacts applicants the moment they apply and runs structured screens around the clock, so you can keep a spring pipeline warm through the slow months without adding recruiters.
