The filing counts its sales and service force and its regions but nothing by segment, so the water, cleaning and pest shares follow segment revenue (c), said so.
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.

By the patterns, the work is about 35% desk work, 12% people work and 52% body work.

Questions about this company
- How much of Ecolab Inc.'s working time is within reach of AI?
- An estimated 19% now and 34% by the end of 2028, on METR's long-run pace at four in five, from the workforce Ecolab 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.
- How many people does Ecolab Inc. employ?
- 48,000 as of December 31, 2025, as its annual report for the period ending December 31, 2025 states.
- What kinds of work make up Ecolab Inc.'s workforce?
- Read from its annual report as a blend of 3 industry staffing patterns, the largest Chemical Manufacturing (3251, 3252, 3253, and 3259 only); by those patterns the work is about 35% desk work, 12% people work and 52% body work. Each share has a one-sentence reason on this page that can be checked against the filing.
- What does Ecolab Inc.'s annual report say about AI?
- 15 sentences in the filing name AI. Its annual reports for fiscal 2021 to 2025 name it in 1, 1, 1, 13 and 15 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 2, 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.
