I voted 3. One of our offices has nothing of the sort - the other has a sick bay that employees can use to have a nap in the event of a real long shift. current project has seen us work from 9 am till 4 am several times a week, with the occasional all-nighter thrown in for good measure. On sleeping patterns, apparently there is a technique where you can train yourself to fall into REM very quickly. Supposedly you only need 2h of REM a day, and once trained, you can pretty much fall into it instantly. then, you just have a 20 min nap every 4h and you get the full amount of rest you need each day! i'd love to try it, but current work/lifestyle doesn't permit it. the idea of only sleeping 2h a day does appeal though! then i'd only be at work 75% of my awake hours, not 95%!
