US jobs grow as work changes within existing roles
Revelio estimates 56,900 US jobs were added in September, while its AI tracker shows most measured task changes occur within occupations.
Changes in the work employers expect people to perform are concentrated within existing occupations, according to Revelio Labs, as US employment continues to grow and hiring demand weakens.
Revelio’s latest AI Labor Market Tracker attributes 90% of year-on-year changes in work activities to shifts within occupations, up from 89% in the previous tracker. The remaining share comes from changes in the mix of occupations across the workforce.
The measure tracks changes in the activity mix described in job postings. It captures how requirements within a role are evolving, rather than measuring the proportion of jobs changed or establishing that AI caused every shift.
Executive assistants, for example, show increasing activity in strategic programme leadership and project coordination, alongside declining accounts payable and invoice processing work. Revelio’s expanded Activity Explorer allows users to examine changes in individual occupations since 2022.
The distinction is relevant for L&D when assessing development needs. A job title can remain the same while the capabilities required to perform it change. In the executive assistant example, the shift towards coordination and judgement raises questions about how development keeps pace with changing responsibilities.
Revelio Public Labor Statistics estimates that the US economy added 56,900 jobs in September 2026, with gains led by public administration and health care and social assistance. Information and transportation recorded employment declines.
Active job postings fell 1.8% from August to September. Eleven of the 16 sectors tracked recorded declines, with leisure and hospitality postings down 14.6%. Public administration postings rose 4.0% and transportation and warehousing rose 1.3%.
Lisa Simon, chief economist at Revelio Labs, said: ‘The labor market continues to add jobs, but both hiring and attrition are still slowing.’
The pace of new AI adoption also slowed. The number of firms newly adopting AI fell 17% in August compared with July, although cumulative adoption continued to increase. This measure sits alongside the September employment figures and covers an earlier month.
Revelio identifies AI adoption through postings for roles that build or operate generative AI systems. It is a hiring signal associated with implementation, rather than a count of every employer using AI tools.
Revelio’s employment estimates draw on public professional profiles, adjusted for workforce coverage and reporting delays. They are separate from official US government employment statistics.
