Often enough they don't care or realize it. I've seen all the data analysts that were eiter (1) senior or (2) also had data engineering skills leave.

They all got 25% more after leaving. And this is in the Netherlands, where pay is already kind of low. What was even weirder was that this company is a F500 company and the people that left, they left for all kinds of organizations (small and large) and still got paid more.

That includes me by the way. I was doing 4 roles (data analyst, pentester, software engineer through web development, AI stuff + data engineering and project manager). It was a lot of fun though. But it paid decisively mediocre.

Currently going to a fun job that pays way better.
