What do you call a co-worker these days? Neither teammate nor confederate will do, and partner is too legalistic. The answer brought from academia to the political world by Henry Kissinger and now bandied in the boardroom is colleague. It has a nice upper-egalitarian feel, related to the good fellowship of collegial.
There does not seem to be that collegiality I referred to there seems to be much more of a them versus us attitude rather than we all have a role to play in this process so let's get on with it.
