One who serially sits on committees

[eldordogne]

Hello all,


I think there is a word or expression in English which we use to describe someone who sits on lots of committees/boards etc.. I think it is probably quite pejorative, or at least tongue-in-cheek, implying they are busy-bodies or overly worthy.

Thanks - this is my first post so hope I'm in the right place!

Not an exact fit, but how about an inveterate joiner?
