This question is a follow-up on a comment at a recent question, where Dave Clarke mentioned that an acquaintance of his has "3 professorships and 2 doctorates".
- How does a faculty member get appointed simultaneously by two or more universities? Are all except one honorary posts?
- Can any faculty member work with a second university with the consent of his present employer? What are the conflicts of interests that come into play usually?
Here in the Netherlands it is relatively common to appoint somebody as a professor for one day a week. For instance, one of the colleagues is 4 days a week at our university and 1 day a week at a different university. Another colleague is 4 days a week working for a company, and works at the university only on Mondays.
