Does Greece have an agreement with the US against double taxation?

BH: Does Greece have an agreement with the US against double taxation?
Does Greece have an agreement with the US against double taxation?? I noticed they are on the list when you apply for the 6166 Form which protects you against being taxed for work in other countries.
However, my temporary employer here is saying that no such agreement exists, and that I have no choice other than to pay the double taxes.
Help!
