Put a mouse trap in your drawer, and check all your colleague's hand the next day and see whoever get the mark. :-P

Kidding aside, you can have your drawer locked, or ask your boss to give you a safety box for such important documents or save a soft copy of it in a USB, carry it with you and just print it whenever you need to. If it is an important document, it shouldn't just be lying around in your drawer.

Really, I am surprised how much paper work is going on around the office, with the technology today Qatar has chosen to stay 20 years behind in terms of documentation. Can't we have a paper less environment in the office! And I am amaze on how many signatories a document must have before it can be processed! Ok, I sound like I am ranting already,,, lol well, I am just sayin.....
