Hello there in Poland : )
Indeed, in the US, there are museum guards who only work in museums. Sometimes, they are called docents. As with most things in the states, however, there is a lot of regional variation.
What's especially interesting here is that an organisation is treating its employees like human beings, as you said. It would be weird for any museum here to say, "I think people would like to know what our employees appreciate in art." Not weird in that it's unthinkable; weird in that it just never happens that way in the States.
