Feeling of superiority among engineers?

Questions to those who worked in cross-department teams (e.g. mixing people from IT and marketing/PR/copywriting): have you ever encountered engineers showing openly that they consider themselves more important part of the team than people from "lower"/"less important" (in their opinion) departments in the company? For example, during a daily stand-up, one of the marketing guys is off (sick leave) and one of the engineers is commenting "No problem, he's not doing that important job anyway". If yes, did anyone in your company/team tried to do something about it?
