You can get carry concealed permits in Missouri.
And I think Texas. I'm sure about Missouri though because that's where I was this weekend and one of the guys out at my friend's house showed me his permit. You have to take a class on gun safety and pass a background check.

Anyway, I wouldn't feel comfortable carrying one even if I could in Illinois.
Working overnights though.. it wouldn't be the worst idea. I'll just keep carrying my mace and taser. The taser isn't technically legal or illegal kind of a gray area. The local police know I have mine and they're outlook is if I need it and I have it - gravy. No crime in defending myself. If I use it "for fun" my ass is getting locked up fast. I'd never do that!
