Not knowing actual causes, but,
I thought Greeks didn't work past 55 and shit like that.
biggest lie ever, the only ones who get an early retiremen here in Greece, are the ones who serve on the military and ONLY the ones who are at the special forces.
Other than that the retirement ages are 67 for men and 65 for women.
Besides, various researches have shown that Greeks are the most working people of the EU.
Editing to make more clear my above sentence :
In the private sector the majority of Greeks work very hard and often very long hours and for little pay, of course there are those that will sling the lead if they can just as in any society, but they are the minority; however, in the public people seem to work less hard, for fewer hours and for much more money.
