" There is a connection, and a close connection, for most unions most of the time. However, there are enough cases of union officials acting to benefit themselves at the expense of their members, both in legal ways and by misuse and misappropriation of union funds, to warn against the automatic equating of the interests of "labor unions" with the interests of "labor union members," let alone with the interests of labor as a whole.
