As an intern in a french software company, I had to suffer from my boss absolutue lack of communication will. The internship was a catastopher : I didn't understood the subject that I initially thought to be a plus in my futur career, and I found myself in that difficult position in where I had to beg for meetings with him, and he wouldn't talk to me for weeks... And when the meeting finally took place, whatever difficulties that I would rise where either minimized, or seen as hard critics...
I think those differencies come from the fact that the modern management techniques aren't so well understood in Europe (let's avoid other cultures), in where there's always been a conflict between bosses and their employees : every single misunderstanting has to end in a conflict (he thought that I was incompetent, I thought the same about him).
