@reasoning logic,
I think you may have intended to post this on Bumblebeeboogie's thread, but I'll answer.
I don't have any objection to labor unions in principle, and I do recognize the beneficial effects of American labor unions in mitigating some very bad labor conditions, particularly in the coal and steel industries of this country in the late 10th and early 20th centuries. However, my (substantial) experience with operating a unionized business in recent decades is all bad. The unions deliberately and forcefully interposed themselves in every and all aspects of management communications with the workforce and worked incessantly to destroy any loyalty to the enterprise (or their non-union co-workers) and the common interests that should have united us all. As one (Steelworkers) Local president expressed it to me, "we don't work your ******* job, we work the contract and the contract is what we make it to be". Very hard to run a successful enterprise under those conditions.
I believe the evidence is very strong that these union attitudes (among other factors) contributed significantly to the early demise of U.S. manufacturing and textile industries. It is noteworthy that (except for Ford) all of the unionized auto companies in this country required bankrupcy & bailouts to continue, while none of the non union European and Japanese operations here did.
Germany is heavily unionized and even requires union participation in the governance of corporations. However, there they have managed to create a sense of responsibility among the unions for the health of the companies that employ them, and, as a result, continue a very healthy manufacturing industry which competes effectively in international markets. How they have done this, I don't really know.
