The filing's table counts its 7,849 employees by segment and country, so Winchester's ammunition plants lead, the chemicals follow and the counted corporate staff take management of companies.
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.
What follows from the reading
Share of working time within reach of AI, on the long-run pace at four in five: 20% now, 31% at the end of 2027, 35% at the end of 2028, 37% at the end of 2030. By the patterns, the work is about 37% desk work, 13% people work and 50% 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 62% of the working time stays with people (conversation, in-person and hands-on work), 31% 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
- How much of Olin Corporation's working time is within reach of AI?
- An estimated 20% now and 35% by the end of 2028, on METR's long-run pace at four in five, from the workforce Olin 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 Olin Corporation employ?
- 7,849 as of December 31, 2025, as its annual report for the period ending December 31, 2025 states. About 86% in the U.S.
- What kinds of work make up Olin Corporation's workforce?
- Read from its annual report as a blend of 3 industry staffing patterns, the largest Fabricated Metal Product Manufacturing (3321, 3322, 3325, 3326, and 3329 only); by those patterns the work is about 37% desk work, 13% people work and 50% body work. Each share has a one-sentence reason on this page that can be checked against the filing.
- What does Olin Corporation's annual report say about AI?
- 0 sentences in the filing name AI. Its annual reports for fiscal 2021 to 2025 name it in 0, 0, 0, 0 and 0 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.
