well, i work for an operation that's 24/7. And not a grocery store or fast-food joint.
Can you describe what you do? (in laymen's terms...not techno stuff...)
I used to work for a networking company (I live in Silicon Valley...there's TONS out here) and would sometimes log on at midnight to work. Not that often though. My job was supposed to be a 9-5 type of job (half the reason I quit). I work in an IT department now for a very large company, and I'm involved in a massive multi-year data center migration now.
