It's time to get serious about residential training rather than obstruct nonunion efforts to do so.
Where I grew up, crossing a picket line was akin to spitting in church. These blue-collar roots have left me with a lingering sympathy for unions, and so has history's legacy of better lives for working people thanks to the efforts of organized labor. Yeah, some unions have a sordid track record of violence and corruption, but if you're going to rattle the skeletons in labor's closet don't forget to resurrect the goon squads and financial crimes attached to the other side as well.
Alas, this pro-union heart finds it hard to bleed much for organized labor these days. Its goal of social justice has morphed into protection of gilded interests. It's hard to muster much sympathy for laid-off auto workers stashed in those misnamed “job banks” where they receive full pay and benefits for doing nothing. Today's union ranks are filled with more government bureaucrats than people who get their hands dirty and bloodied. In my hometown of Chicago, too many trade shows are hightailing it to other cities due to featherbedding work rules among the unions working at the city's otherwise splendid exhibition facilities.
