Yep, exactly, although that's a big statement to try to have in your head all at once. XD

I guess in the context of electric fields work is applying a field force over a distance?

Yes, but don't generalize that too far -- you can't expand W = Fd into W = (ma)d naively; you have to make sure that expansion makes sense in the context.
