I used to work in the Voluntary Sector, in a role funded by the Gvt. Really big salary. Nice job, responsible for own workload, diary, etc. Lots of reports and justifications, though, but the salary more than made up for it. Only drawback, it was a 12 month fixed term contract, and every year there was the uncertainty that the funding would be withdrawn, and therefore no job. Of course, the funding was withdrawn, so now I am a poverty-stricken sole trader...! Life's fun, innit?!
On a more serious side, many of the positions in both the Voluntary Sector and Charity side pay silly salaries for very little work; most of it consists of attending networking meetings and funding meetings (where all the same people are, anyway, instead of working) there's a lot of talk going on and not much doing, which I had a problem with. Many of the positions are so open to abuse, it's ridiculous - I know, because towards the end of my contract, I abused it horribly, going to the gym or having my car fixed during working hours; with a little diary manipulation, it was easy. Personally, I would definitely not employ someone who has worked in these sectors without a lot of thought and background-checking. (Sorry if you are one of the good guys working for them - I was to start with.)
