that may have been part of their original intent, but it's far from the truth today. Unions continue to exist, even though there are hundreds of laws protecting employees from unfair labor practices and unsafe work conditions, mainly to make money off the dues. They don't really care about the workers, despite all their talk. I've been in 4 different unions, and I couldn't wait to get away from them. They force companies to hire three to four times the necessary work force, pay everyone the same high wage, despite any work performance, and cause all work to be done at a drastically slower pace just so the employees can keep milking a job. The only people that benefit from unions are generally the worst employees who would have been fired ages ago, but now can't be because of the unions. if the files clerks back in 2002 were averaging $40 an hour, what could the guys doing all the real work possibly be making...?
While I take the point you are making.. if you have not had a bad experience at the hands of corporate management, then you effectively did not require those Unions services.. and therefore the fees were a bit like the payments on an insurance policy, where you have never needed to make a claim.
I have had a number of friends who do not work in industries that traditionally use Unions, ripped off for literally tens of thousands of dollars commission on corporate Sales contracts, when their management realised that the commission on their Sales performance, would exceed an amount the management was 'happy' to pay.. in most cases because it meant the employee, would earn considerably more than their line manager/s.
The terms of their employment were therefore unilaterally amended by the management, without agreement from the employee.. In all cases although those friends were covered by some of the 'hundreds of laws protecting employees from unfair labor practices'.. there were two significant problems:
1. Paying in hard cash and time to pursue those legal entitlements.. I once processed a claim against a company over an unpaid bill, it took two years to get to court..and I was being paid as part of my job, to nail the SoBs.. it is a very different matter to pursue legal action at your own expense.
2. The awkward issue of getting a favorable reference from a company you are sueing.. because lets face it, once you start the legal process, your career is over at that company.. and win or lose, quite possibly in that industry.
As a result in each case, those individuals found jobs working for other companies, but had to swallow the financial loss.. so I don't have much sympathy for the implication that corporate management is all 'good employees' need..and that the market does not need Unions.
I have worked in management and I have worked on the 'shop flloor'.. so I am a tad cynical about both.. I certainly don't subscribe to pixie dust Libertarianisms about the market.. the market does what it does, badly.. however until someone invents something better, imho it's the best we have got.. but please don't put lipstick on the pig.
