Why do universities need unions? Etymology! It’s probably clear that both words come from Latin unus “one”. A union is a collection of workers. You might have thought that the word university reflects the idea of universal education or the universal coverage of subjects, but in fact it’s short for universitas magistrorum et scholarium, the union of teachers and students. The university started out as a kind of scholastic guild to protect their interests against outside, non-academic forces, reducing the financial barriers to education and protecting the livelihood of the teachers.
