Youth riots in France

From the articles in the FT I can hardly tell what is going on in France. The youth seem to be protesting a ‘bill’ in the legislation that would allow private companies to terminate the employment of people aged 26 and younger in the first two years of working due to non-performance. What is the problem with that? When I get a non-performing intern I let my company know; I believe that work ethics are formed well before the professional working age.
