No disrespect but that chart is just a stating Greeks have longer work hours on average than other European nations. That doesn't mean one of the most hardworking. Those numbers are skewed. Other nations, like Germany, have more part-time workers which bring down the national average. They also have more holidays, sick leave, maternity leave, etc.
Also Greece has a much larger agricultural sector (longer hours - just like Portugal and Spain) and shops stay open later which creates that discrepancy ....
The perception across the board in Europe is of the contrary ...
I'm sure that the perception may be based on inaccuracies but what I stated was that Greece was VIEWED as the least hardworking. Which they are (Viewed).
Doesn't mean it holds true and I honestly wouldn't know since I don't have that perception personally of anyone in Europe since I consider Europe in general a more hard working population than many other areas....
