Sir, I know that you are simply trying to stir up people. But if you do indeed believe that unions bring down companies, you have not thought enough about how companies work.
A leader of a company with a unionized workforce has three groups to deal with: Management, Employees (Union), and Customers. His job is to get Management and Employees on the same side, working for the customer. Any company in which people refer to "Union Guys" vs "Company Guys" is destined to fail.
If you think this is not achievable, you really need to look at various unionized companies and watch how they perform brilliantly. Delta management before Ron Allen did just that. A great leader will galvanize his people, union or not. Unions are made up of employees. Satisfied, appreciated, fairly-compensated employees will act reasonably within their union, and you will see a company that operates essentially like a nonunion company.
The problem with Delta is that Allen and Mullin themselves were not on the side of their own company or customers. Allen was an incompetent leader, and Mullin was busy raiding whatever he could from the company and allowed the unions to the same.
I am not anti-management. If you have several hours, I will describe some of the greatest minds in the business. It just so happens, and this is well-documented from some great business analyists, that airline management historically has been poor. This is really a shame, when you think about it, because of all the industries out there, airlines can be really fun to manage as well as to work for as front-line employees. You would have hoped the bad managers would choose to work in less glamorous industries, like Plastics. A real shame.
There are a few notable exceptions, and these leaders have inspired their employees--unionized and nonunionized--and made their airlines great.
