The Rangers captain recently criticised former boss Neil Warnock on the social networking site.
Asked whether the midfielder's tweets were a cause for concern, Hughes said: "No, not at this stage. Joey understands what happens in the dressing room stays there and I don't think it will be a problem.
"If ever I felt that it was going to compromise us then we'd have a conversation and talk it through, but certainly I haven't felt the need to do that up to this point."
