None. However in ages past, public employees were a small fraction of the population. However, since the early/mid 20th century, they have been multiplying like plague rats. In some countries, like Greece, they now outnumber the peasants.

I wonder: In what age, in what government, have public employees acted otherwise?

Seems to me this is a universal human trait – – not the product of communism or capitalism or corporations or Democrats or Republicans or Muslims or Jews, or Christians, or any other of the typical scapegoats commonly blamed for the harm caused by self-dealing people, whether in private or public occupations.
