Pros
Pretty much everyone who works there is nice and there is a genuine positive attitude towards caring for its staff. Salary's are good but these days you can forget about getting a pay rise whilst staying in the same job.
Cons
I've been there over a decade now and there's a re-org every 2 years, for me its been 50/50 whether I'd have to apply for my job again. Every second re-org is a massive one, my last smaller re-org hadn't event finished before the current bigger one kicked off. One of the main departments has just reduced by a third and 20% of the remaining jobs are now listed as a new entry level job. Its starting to feel very much like a dying business. I've had a question mark over my job for the best part of a year now. Its horrid. EDF used to feel more like a family but now its soulless. Cost of living increases are better than nothing but you'll be lucky to get over 0.5%
