Don't take more than two weeks at a time vacation let alone loose access to your email if you value your job. Ever. While we get there all esoteric on taking time off to rewind because we have added so much value already and the world is beautiful a worth exploring, there are many people working non stop to take what you have... bummer
This is terrible advice. One of the most important things in security (amongst other practices) is to ensure that people take regular longer breaks, because it's a great way of seeing where there are dodgy practices going on, and in particular people making themselves SPOFs. If you have inherent value, rather than just a castle defended by a moat of failing to cross-skill your colleagues, then you'll be safe taking longer holidays.
