I was thinking something similar. "Queen" implies a sort of authority or social dominance which, AFAIK, is not generally present in eusocial species. The "queen" is an egg factory, not a leader, and the workers' relationship to her is more like engineers:factory than attendants:royalty.

I'm okay with "worker" as a name because it's a literal description of their behavior, but you're right that it shouldn't be interpreted as a social status.
