I didn't like this article at all. First - it states that putting insane pressure on people to work long hours is counter productive - and mandating week-end work leads to burn out.

The very next sentence then immediately says this:

"People who love their job and the company will work all the time anyway. If you’ve hired good fits, you’ll see this happen."

Uhh.. so you want to replace mandatory week-end over time, with an informal criteria where good fits work all the time anyway - thus if you don't work on the week-ends (of your own """choice""") you confirm you aren't a good fit?

Now, there's nothing wrong with working on week-ends when there's a deadline or an important milestone, but substituting explicit expectations with implicit ones is flat out horrendous and it means that you have to constantly read between the lines to find out exactly what you have to do.
