The job of the union is to take the business interests and then keeping that as a constraint, maximizing labor's share of income. This usually directly means having the right people in the right places, to do an effective job, so there's not much time wasted. (Which is their time.) And so on. Unions shouldn't try to keep everyone on board, they should simply counteract shareholder pressure to keep labor costs down. Of course, the union should help members to retrain and then should help those members to find their place where they can contribute value. Of course, the union can and should represent the political values of its members.
