I remember I got home from work on a Friday night once, kicked up my feet, ready to relax, unwind and watch tv. I got a call because one of the systems shat itself and I had to go back in to fix it. Another time I recall my boss got a call at like 3am because his boss (the lazy fuck) told him to go into the data centre and fix something else up. I'm over all types of being "on call" for shit and putting my on welfare at risk for the computer systems. No thanks. It's not the end of the world if something fucks up.
