Build a workforce trigger list

A workforce trigger list turns corporate news into a prospecting map: layoffs, executive exits, funding rounds and mergers can signal a space move before a lease hits the market. (dol.gov) The layoff piece is the easiest to verify. The federal Worker Adjustment and Retraining Notification law generally requires covered employers to give 60 days’ notice for plant closings and many mass layoffs, creating a public paper trail before some office contractions show up in brokerage data. (dol.gov) The law defines a mass layoff at a single site as either at least 50 workers and 33% of staff, or at least 500 workers, excluding part-time employees. That makes WARN notices a concrete trigger for downsizing, sublease marketing or a pause in expansion plans. (uscode.house.gov) Executive turnover is a softer signal, but it often arrives before a portfolio reset. The Real Deal reported on January 27, 2026 that Douglas Elliman’s head of residential leasing exited after 10 years, one example of how leadership changes can precede shifts in leasing strategy and footprint decisions. (therealdeal.com) Mergers create another clean trigger because overlapping offices force decisions on consolidation. The Real Deal reported on February 5, 2026 that the Fifth Third–Comerica merger left a 60-story Dallas tower “in limbo,” tying a corporate deal directly to a lease question. (therealdeal.com) Funding is the opposite signal. PitchBook and the National Venture Capital Association said in their 2025 Venture Monitor that capital stayed concentrated in artificial intelligence while deal counts fell, leaving a smaller pool of startups raising larger rounds and needing room to hire fast if growth holds. (nvca.org) CB Insights said its 2025 AI 100 list drew from more than 17,000 companies and ranked startups on market traction, investor quality and talent. For brokers, that kind of funding-and-headcount screen is a practical way to separate AI firms likely to need expansion space from startups still too early for a lease decision. (cbinsights.com) The office side of the market still favors efficiency. JLL’s 2026 global outlook said occupiers are operating in a higher-cost environment, while its April 16, 2026 fit-out report said office build-out costs rose 2% to 6% across regions over the past year. (jll.com) (joneslanglasalle.com.cn) That cost backdrop explains the two campaign lanes in the briefings. Large companies reacting to layoffs or mergers are more likely to respond to cost and flexibility, while venture-backed AI companies coming off funding rounds are more likely to respond to speed, power capacity and room to grow. (jll.com) (nvca.org) The list only works if it is updated constantly. WARN filings, company funding databases, executive-move coverage and merger reports each catch a different stage of the same story: whether a tenant is about to expand, shrink, relocate or wait.
