Unions are a bad solution to the problem of companies not vaulting their employees. Unfortunately, without altruism by the corporations or governments action, they are also the only effective solution.

I'd prefer we look to other countries that have solved the problem in other ways, such as including representatives of the employees in the board.

Also, we need to remember that corporations exist at the mercy of the state, having received a special dispensation (corporate charter) to exist. Those companies that are not a net benefit to society have no right to exist and ought to be dissolved.
