French government's caution on pension reform a "mistake" - union chief

PARIS (Reuters) - President Francois Hollande's plan for a cautious reform of the pension system is not extensive enough, the head of France's largest union said on Thursday.

Laurent Berger, who heads the reformist CFDT union, criticised Hollande as unions, employers and officials launched three months of talks on how to fix a pension system seen running a 20-billion-euro (16.8 billion pounds) deficit by 2020.
