Fajwat's just bitter because he's never worked outside of soul-dead corporations. I'm fairly sure that both my bosses know that if/when I leave, the library will be SOL. I'm the only one who knows the webapps (which are critical to the library) and the web side of the catalog, of which I'm redesigning, currently. And it wouldn't be a pretty sight if I left.
I got two raises in the space of two months and I'll be asking for another one or two by the end of the year.
