Just finished my apprenticeship with a large pharmaceutical company, they paid for my degree and I studied part time for a BSc hons in Applied Biological Sciences. I do enjoy my job but it isn't particularly well paid considering the hours and dedication required. Pharmaceuticals as an industry seems to be falling apart at the moment (Pfizer closed a site in Kent yesterday making 2400 unemployed) and GSK did the same last year but the amount of redundancies was a lot higher than this. So, I enjoy my job, being a scientist is like doing a massive puzzle, and I love the fact I have to think "outside the box". However, I feel I ought to change as well if I want to earn some proper money. Same boat as you mate
My future options: PhD, work my way up through my company, change job, retrain.
I am as confused as you are
However, I agree with most other people on here, DO NOT LEAVE UNTIL YOU HAVE FOUND SOMETHING ELSE TO DO!!!
