Work Life Balance

Disclaimer First - I am not an authority on this subject. However like everybody else, I have my feelings and i thought i would share my thoughts and experience.
I think every website that you come across would boast about maintaining a healthy balance on Work - Life front. However a look beyond the skin would reveal there is little organizations can do to maintain this balace. Such is the intensity of business, pace of technology and pressures from competition.

First of all thanks to the mobile phones, now blackberry's you are always hooked on mails and yeah while response times are faster it also means people are actually spending more time on work than they used to previously. Result - Burn outs. A point also echoed here

This is also becoming evident as a lot of people at the top of hierarchy are suddenly leaving their jobs across the world. This makes one wonder what organizations can do best to something which has become a verbal promise ?
Any answers? As i said before am not an expert, so seek your opinions.
