Federal Signal’s approximately 5,800 employees, 60% of them U.S. hourly workers, build sweepers, vacuum trucks and dump bodies and make warning systems, split by description.
The figures on this page come from the company's own annual report and from BLS staffing patterns for its industries, never from a roster. They are estimates with a stated method. Nothing here says what the company will do: within reach is not a forecast of jobs lost or of savings.

Questions about this company
- How much of Federal Signal Corporation's working time is within reach of AI?
- An estimated 17% now and 28% by the end of 2028, on METR's long-run pace at four in five, from the workforce Federal Signal Corporation's own annual report describes and BLS staffing patterns for its industries, never from a roster. It is an estimate with a stated method. It is not a forecast of jobs lost or of savings, and it says nothing about what the company will do.
- How many people does Federal Signal Corporation employ?
- 5,800 as of December 31, 2025, as its annual report for the period ending December 31, 2025 states.
- What kinds of work make up Federal Signal Corporation's workforce?
- Read from its annual report as a blend of 2 industry staffing patterns, the largest Motor Vehicle Body and Trailer Manufacturing; by those patterns the work is about 30% desk work, 16% people work and 54% body work. Each share has a one-sentence reason on this page that can be checked against the filing.
- What does Federal Signal Corporation's annual report say about AI?
- 3 sentences in the filing name AI. Its annual reports for fiscal 2021 to 2025 name it in 0, 0, 2, 3 and 3 sentences, year by year. They are counted and quoted on this page, never judged: a count says how much a filing talks about AI, not what the company does with it.
- How is this estimated?
- Claude Fable 5.1 read the annual report under the Index's written rubric (version 1) on October 19, 2026: the stated headcount, the share in the U.S. when stated, and the workforce as a blend of industry staffing patterns. The estimates are the site's industry estimates weighted by those shares, from O*NET tasks with estimated lengths and METR's measurements of how long a task AI models can finish. A company can write to info@stratussc.com to have its reading checked against its filing.
