ZURICH, June 24 (Reuters) - Fewer junior positions are being advertised in Switzerland than before ‌2023 as firms increasingly adopt AI, a ‌study by Swiss job portal jobs.ch published on Wednesday showed.

The ​share of entry level roles advertised in Switzerland was 32% lower in 2025 than the average between 2019 and 2022, which the study defined as ‌the "pre-AI" phase.

The study, ⁠which looked at over 7.3 million job advertisements, said marketing, administration, finance and ⁠IT were especially hit by the adoption of AI.

At the same time, AI skills were increasingly ​sought in ​positions outside of IT ​work and offers for ‌senior positions rose 26% in AI-exposed roles in 2025 compared to the four-year period before 2023. Junior positions in AI-exposed-only roles, fell 16% in the same period.

Demand for junior positions outside of ‌office and research spaces meanwhile ​remained strong, particularly in ​healthcare, construction and ​trades with persistent shortages.

When surveying more ‌than 3,600 workers, 41% of ​under 25-year ​olds said they are worried about becoming less valuable in the workplace because of AI, ​or have what ‌is known as AI "FOBO" - the fear of ​becoming obsolete.
