Does your company allow 'reading holidays'?

The 'innovation time' ideas used at companies like Google and 3M are well known instruments to encourage innovation, with Google offering 20% of an employees time towards personal projects.

So it was interesting to read of a similar kind of thing at Microsoft, whereby Ray Ozzie, and before him Bill Gates, would allow themselves reading holidays.  These are essentially week long breaks where they would devour books on a wide range of topics.  The reasoning was that the usual hectic work week doesn't really allow time to truely read, and such is the importance of reading well and reading widely, that this was implemented.

Obviously in the context of 1 day a week devoted to personal tinkering a week devoted to reading shouldn't be a big deal, yet I haven't heard of a similar concept employed anywhere else.  At MS it's called Think Week (see below a video from Gates talking about it)

Do you have anything similar at your workplace?  Would you benefit from a 'think week'?
