Why entropy change associated with work is zero?

You sure that's correct?

Reversible work, at least. I've seen an interpretation of this in McQuarrie's Statistical Mechanics. He describes reversible work as a raising or lowering of the energy of all the microstates, but not a change in the number of microstates. Thus, the system entropy is unchanged. During heating, however, the number of microstates changes, and so does the system entropy.
