My experience of Bulgarian employees has been, frankly, mixed. Those that have studied or worked in "the West" are often as good as any workers you can find anywhere in the world. Those that have only limited or non-existent experience outside the country can be really terrible to work with. Lazy, dishonest, arrogant, unable to work properly, always late, with a sense of entitlement that beggars belief. Not all are like this, but quite often it is the case.
