I'm wary because unions in the US start out strong by addressing very real grievances and putting the greedier aspects of management in-check. But it seems inevitable that they become entrenched, bloated, and protectionist to the point of hurting the company's ability to adapt to market pressure and disruptions from non-unionized competitors. I'm not anti-union per se, and I would rather see them structured the way they are in Europe, and particularly, those in Germany.
