i guess it depends on the job, and it depends on the two peoples' working styles.
I know some people who I would be able to work together well with, as both coworker and roommate.. and others who I most definately would not. most fall in the "not" category.
its an interesting concept to consider, though: that perhaps if two married people cant work together.. then maybe there is something seriously missing/out of whack with their relationship.
(ie: positive conflict resolution, for one?)
