In Germany, those counting the polls are often associated with the parties, so you actually often have party members (at least of the biggest parties) involved in the counting. But because any party can contribute + there is free access for observers, this is a non-problem. Actually I believe it's a feature, as it would (politically) be a lot harder to argue for the poll workers to be one-sided if your own party members are part of it.
