We are pretty much all-in-one techs. We have a network admin, one person who manages our work orders, and one "superior," who handles the business aspect. Everyone else in our department is expected be able to troubleshoot basic hardware issues, fix printers, troubleshoot network issues, build images, work help-desk, write basic batch files for troublesome installs, breathe, walk and chew gum at the same time, etc. If one person doesn't know how (or isn't in the mood) to handle a certain situation, then they are expected to contact someone who does.
Possibly the reason that some of our techs feel the need to be reluctant to try something new, is the fact that they are simply "expected" to do the work of 6 different areas of IT, but only get paid a third of that. I'm a youngster, apparently, and am somewhat satisfied with the money that I make, where others are not.
