yea, I never said that. I was just describing what the vacations are. If you think that they don't do research you are partially right because of a lot them don't do it after their permanent status.
Do Professors really have three months of vacation in Canada? I assumed you meant 3 months without classes (which is totally different from vacation). I find it hard to believe that they would get 3 months of vacation.
I am from Austria, and here and in some other European countries typically one has about 5 weeks of vacation per year, so 3 months sounds like a lot. How many weeks of vacation do other people in Canada have, for comparison?
Interesting. That seems to be quite different from any other system I've encountered so far. Hereabouts being a professor is an all year job (with usual vacation times), with the two-fold task of doing research as well as doing teaching.
The time periods in which there are no classes are usually used by professors to focus more on their research and take their vacations (5 weeks per year like everyone else). Similarly, these time periods are not strictly holidays for students, with many students taking exams.
I've seen a few professors simply neglect their research and take the whole time period where they don't have classes as "vacation", but this seems to be limited to a few older professors who are still state employed, basically untouchable and seem to have lost their motivation over the years. They usually seem to not do much research at all anymore, but are often willing to pick up additional teaching duties to ease the load on their colleagues.
Most people however do actually work on their research in this time period.
