The aim of my study is to discover what IT professionals need to be satisifed at work

U could probably mine Perlmonks.org to get an idea on what Perl focussed IT pro's *cough* need to be satisfied at work. Eg this link has got some interesting thoughts on the subject already.

One thing you could include in your study to make it really cool is to research the correlation between certain likes/dislikes of people and the technologies they use...eg perl-adepts will be happy at work if you give them IRC access, while vbscript programmers are satisfied as long as you give them their monthly copy of the MSDN etc..
Maybe you could even try and extract some sort of psychological profile of people in different technology areas. I think a lot can be said about a person leaning towards *nix and GNU type of products, just like one can tell a lot about someones attitude if you know he's heavily into MS stuff..
The study will certainly be valued by IT managers and the likes, who sometimes don't seem to understand why brilliant young programmers choose to go and work for a company 'with a cool attitude' rather than some boring bank paying big nachos

Note: I emailed this link to the author as well
