It may seem weird, but it is standard operating procedure at many, if not most shops with computer networks. The tradeoff looks like this: the knowledge potentially preserved & transferred in 2-4 weeks of continued access for everyone is worth far less than the same access used by a disgruntled now-ex-employee to steal IP or do damage. Even minutes of access to the wrong person is a significant risk. Plus, if there is a really important or tangled question that only you'll know, they can hire you as a consultant later to sort it out, if needed. So, wherever you work, be sure to plan and structure your information as if your access can be cut off by surprise at any minute. Expect only zero notice, and to be marched to the door by security, with somebody else packing your personal stuff into a box and delivering it later. If you get more, consider it a bonus. Remember, none of this is personal, any more than being required to walk through metal detectors at so many places is personal. It is all about risk management.
