Not getting into the whole sticky debate of whether a man could/should seek other employment if in fact his family can't manage with him being gone so much, let's look at qualifying that time.
I submit that in a family of perpetual parturition, it is not feasible for a husband to *choose* to spend more time at work than is neccessary to make a living for the family and at the same time fulfill his role as husband and father. Notice I don't draw the line at barely maintaining sanity. No, we're talking about fulfilling-- as in FULLNESS.
On the other hand, I recognize there are situations in which the number of hours a husband must work to make a living wage is more by neccessity. I'll mention that again later.
As my brain has shut down for the evening, I'll have to leave it at that for now.
