Many researchers trained at universities find it very difficult to start a post-academic career in industry.
After many years in the university world, working on their PhD thesis and/or doing one or more postdoc contracts, less than 10% of university students will make an academic career, with even less achieving a full Professor position. Furthermore, early career academics are not trained for a career in industry.
As a result, there are more PhD students, postdocs and researchers on the market with similar academic CV profiles looking for their first job in industry/outside the university/the scientific world. Many academically trained researchers feel frustrated when they realize that the world outside academia is not what they expected.
They feel misunderstood and their self-confidence decreases during the job hunting process. Therefore, many researchers prefer to remain as postdocs at universities, as this is the career pathway they are familiar and comfortable with. This is understandable, as leaving academia is a step out into the unknown.
Academically trained professionals must learn what they can contribute to industry and society, as well as how to present and market their skills and competences.
