Working from home is not allowed at our place. I worked from home more when I was in industry than I do now (unless you count the sitting up at 3am correcting a PhD thesis so the postgrad can have feedback quickly as "working from home". My colleagues and I seem to do that an awful lot). In addition to teaching, we are also expected to:
develop our own research groups,
generate a minimum of £100k research funding per year (each grant takes around a month full time to write and has about a 10% chance of being funded)
take on a certain number of international PhD students each year (do you realise it is not easy to get someone through a PhD if they barely speak English?),
carry out peer-reviews of papers, books, research grants,
editoral board memberships,
funding body advisory boards,
publish a minimum of 4 peer-reviewed papers per year in "good" journals,
give conference lectures,
physically carry out research (which includes developing collaborative links within and outside the university),
carry out admin tasks such as serving on various university committees, coordinating modules, leading teaching groups etc etc etc,
exam/coursework marking,
being part of the exam board,
external examining for other universities at both undergrad and postgrad level
personal tutoring for undergraduate students
These are all fairly minimal tasks required to be considered to be doing your job reasonably. They are not even exceptional responsibilities.
There are be a ton more things I could add to that list.
