About to go on a 7 day vacation/holiday. Not a great time for it at work. Two of our major clients are about to go live with our system and I wont be there to babysit them.

I think you can tell when you have become a corporate slave(I am just a humble corporate slave, working myself into a corporate grave), it's when you feel guilty taking time away from the office.

Mind you - I do enjoy where I work, and leaving for any time tends to mean i miss stuff when i need to see whats going on.
