That was an interesting article, but I really didn't like the phrase 'shields down'. It sort of implies that the default state, that you should protect, is keeping your current job. I think the default state should be you being happy, fullfilled and well compensated in your job. And if you take a better offer somewhere else, it's not because you 'dropped your shield', it's because you're looking out for your own interests.
