Mandatory vacation.  This is something that the finance industry has used for a long time to guard against fraud -- it's hard to cover up something if someone else has to do your job for two weeks straight at some point -- but it also serves as a mechanism for requiring you to cross-train people.Two weeks of paid vacation where the company isn't allowed to email them or call them for help: I guarantee that documentation practices will increase substantially.
