Notwithstanding the well-being agenda, it seems, at last, we are recognising the damage done to family life by the long hours' culture.

I wrote an article some years ago about what makes a successful marriage. In summary 'frequent partings' - have your own separate interests and something to talk about at the end of the day, and 'increasing deafness'(!) - don't take too seriously everything your other half says to you. I would add a third - make time for each other. It really is crucial.
