What follows from the reading
Share of working time within reach of AI, on the long-run pace at four in five: 17% now, 34% at the end of 2027, 42% at the end of 2028, 47% at the end of 2030. By the patterns, the work is about 47% desk work, 14% people work and 39% body work. These are the site's industry estimates weighted by the shares below: estimates with a stated method and range, not a forecast of what the company will do. By the same patterns, at the end of 2028 about 51% of the working time stays with people (conversation, in-person and hands-on work), 39% becomes checking a model's work and 5% could be handed over with lighter checks, from the industries' own figures, not the company's roles.

Questions about this company

- An estimated 17% now and 42% by the end of 2028, on METR's long-run pace at four in five, from the workforce Littelfuse, Inc.'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.

- 17,000 as of December 27, 2025, as its annual report for the period ending December 27, 2025 states.
- What kinds of work make up Littelfuse, Inc.'s workforce?
- Read from its annual report as a blend of 2 industry staffing patterns, the largest Semiconductor and Other Electronic Component Manufacturing; by those patterns the work is about 47% desk work, 14% people work and 39% body work. Each share has a one-sentence reason on this page that can be checked against the filing.
- What does Littelfuse, Inc.'s annual report say about AI?
- 1 sentence in the filing name AI. Its annual reports for fiscal 2021 to 2025 name it in 0, 0, 1, 2 and 1 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.
