Xerox in Welwyn Garden always have jobs available. If she wants to use her degree then Glaxo are just up the road in Stevenage, and Roche are in WGC. According to Google there's this place too http://www.biopark.co.uk/The only other problem, despite moving down is finding my girlfriend a job. She has a 2.1 from Leicester in a life science and would be happy doing any old office job. Even if it's just temping until she finds something permanent!
For the love of god man live in st albans!
I live in Hatfield for Uni, the Uni is good but the town upsets me!
If you do move down to St Albans, drop me a line, I pride myself on knowing all the best pubs in St Albans!
EDIT- Saying that there are some alright places in Old Hatfield.
