comment As a department head, what to do if a professor leaves without giving out grades?
The exams themselves may be stolen property, you might even be able to involve the police if the fugitive is still local. (Again your school's lawyer will know more about this kind of option.)

comment Department not giving me TAships after a dispute with professor, what should I do?
If you have a union, this is exactly the sort of thing they're for.

comment What should I do if a professor says she doesn't understand my questions in office hours?
I assume this answer is referring to the underlying mathematical questions and not to the question asked here.

comment How to proceed with a type-theoretic proof that $\Sigma \mathbb{S}^1 \simeq \mathbb{S}^2$?
I'm a bit confused about what your definition of $\Sigma S^1$ is. I would have expected it to be generated by one point, one 1-loop, and two 2-paths trivializing the 1-loop. But you seem to have two points. Could you clarify your notation a little?

comment In a closed monoidal abelian category, are the compact projectives a monoidal subcategory?
If your tensor category is finite, then compact projective is the same as projective. In that setting, tensoing a projective by anything is projective, see Prop 2.1 of arxiv.org/abs/math/0301027

comment How to handle a student's public speaking anxiety when teaching a class that requires presentations?
A prerecorded video presentation would be another option along these lines.

comment What is the recommended option for a faculty applicant after accepting an offer and getting another better offer?
There are good reasons for this difference between academia and industry, which is that academia is built around semester and year calendars. Leaving an academic job mid-semester would be a disaster, so even non-tenured faculty are typically on year-long contracts rather than at-will like in industry. This is also in the interest of faculty, since there aren't jobs offered all year round. These differences run both directions, which is why it was such a scandal when Microsoft Research laid off a bunch of academics without advanced notice and while paying no regard to timing.
