I've addressed this... about ten times, or so. Maybe list a list form will help.
I believe unions tend to actually harm their members for the following reasons:
1) Unions tend to make it difficult or impossible to promote exceptional workers.
Workers are promoted based on seniority and other qualifications in a Union workplace. There is no doctrine to suppress the exceptional.
2) Unions tend to make it difficult or impossible to fire deficient workers.
Job security is a definite Union benefit. However, the bad apple eventually does him/herself in and usually it's Management laziness that lets them stay on. Union's have no interest in having a bushel full of bad apples. We do vigorously protect workers from the ever changing definition of "deficient".
3) Unions tend to suppress wages for new and/or inexperienced hires.
Interesting that you suggest this when most companies will not start out new or inexperienced workers at a high wage and some invoke the lower-than-minimum "training wage". I see no real Union disadvantage here although perhaps you are mistaking the Union value of dedication to a career. We aren't here for the fly-by-nights although that seems to be a value for your generation. Trade Unions have "apprenticeship" programs where a new hire gets valuable on-the-job training for a reduced wage, hardly a trade off.
4) Unions tend to suppress raises for new and/or inexperienced hires.
Untrue as every contract I've ever seen has a defined raise after a probationary period.
5) Unions tend to promise benefits that, in the long term, they cannot actually afford.
I assure you that our benefits are much more stable than anything you can provide yourself or the Government will. Sure, there are some lackluster pension plans but those pale in comparison to the eventual demise of Social Security and the corporate thieves that forced employees to buy company stock that we eventually worthless, for example.
6) Unions tend to demand no pay cuts, and end up with more people laid off instead. Union's don't operate in a vacuum. During the negotiating process Union's are entitled to privileged information about a company's financial status and make their demands accordingly. It isn't in anyone's benefit to have layoffs or an unhealthy company.
7) Unions can demand fees from employees whether or not the employee appreciates the union.It's our job to educate you so that you'll appreciate what we have negotiated for you.
This list is non-exhaustive. It's only what comes to my mind at the moment. However, there's a couple major points I'd like to add: the effect of unions on laws and monopolies.
On laws: Union lobbyist support laws which severely harm the economy. These laws, I believe, actually make it difficult to get a job, bankrupt companies, reduce competition, and slow the economy. These lobbyists end up increasing unemployment, and decreasing wages of the economy as a whole.
As with your education argument, you are making the Glen Beck argument that Union's are to blame for all of the economy's ills. You are certainly entitled to your opinion, but not your own facts. Show me where a large percentage of bankrupt companies are Union. Show me where unemployment is the Union's fault. Show me where Union's are reducing competition or where a Union company doesn't compete against a non-Union one. As for wages, look to none other than the Dept of Labor, Bureau of Labor Statistics where you will see that Union workers on average make 28% more than their non-union workers. In fact, Women, African Americans, and Latino's all average better than 29% more in wages over their non-union counterparts.
On monopolies: Unions within monopolies, such as government employees, are extremely harmful. Because they have no competition, there is no check or balance. If UPS becomes inefficient, then FedEx will crush them. Therefore, the UPS union must be reasonable in its demands to management. Government employee unions have no such competition, and so can make all sorts of ridiculous demands, and get them. They get benefits and wages at the cost of everyone else who pays taxes, regardless of economic downturn, efficiency, or positive outcomes.
This would seem true until you look at the wages of Government administrators and department heads in comparison to the workers. Government is the problem, not Government unions.
So, again, to summarize: I think unions tend to harm the economy and employee in general, so I would not appreciate their "help," so I would not be a hypocrite by any definition.
