A quick Google search found :

The Website for Tilburg University's Flexicurity Research Programme "Flexicurity: A New Paradigm for Labour Market and Employment Regulation?" can be found here

A paper by Dr. Ute Klammer, "On the path towards the concept of "flexicurity" in Europe" in pdf can be found here.  I found this paper very enlightening.

The European Trade Union Institute has funded a research project whose web page can be found here.
I quote from that web page for comment:

Flexibility seems not only to be the monopoly of employers since employees and their representatives also show a need for a more flexible organisation of work in order to meet employees' individual preferences and circumstances, e.g. in combining work and private duties and responsibilities on a life-long basis.

The concept is interesting but I also see some issues - to put it mildly.
