Work at Uni and fit in with your timetable is the best benefit. You decide when you want to work. You get to know more about the Uni.
The benefits are fairly standard for a UK university, but I should explain that it's nearly impossible to get promoted at Exeter University -- the management tries to limit promotions in order to keep costs down. This is one of the many reasons for the high staff turn over -- people learn to move to another university if they want to get promoted.
No pension is offered, no perks or benefits at all. There's a huge disparity between those at the top flying everywhere first class and being driven around in the University-owned chauffeur-driven limousines, and those of us at the bottom being told there isn't enough money to have individual rooms in a Travelodge...
