Vantaggi
Very generous annual leave, although you won't get to use it because you can't during teaching time and you will need to write grants during the summer, otherwise your career will end. You will be asked to manually mark hundreds multiple question tests, which is a pro if you are one of those people that are against machines replacing humans. Pay is good (until you calculate an actual hourly rate, given that you will regularly work weekends to stay afloat).
Svantaggi
It seems like a lot of the 5* reviews on Glassdoor come from student ambassadors and temp workers, which suggests a covert system for doctoring reviews where the institution encourages reviews at the end of zero hour contracts. In reality, the place is going through the second voluntary redundancy scheme in a year, and people who have retired / resigned will not be replaced, leaving those who remain (and the unfortunate new hires who trusted the reviews) to pick up the pieces.
