You might have misunderstood my point, or, probably, I didn't use enough words. The union's continued health depends on it's making unreasonable demands that will never be met and convincing it's members that everything that's bad is management's fault.
OTOH, your shop is a perfect example of why I will never again willingly be subject to collective bargaining. Collective bargaining guarantees that exceptional employees will never be compensated any better than the mediocre or marginally competent employees. It can, perforce, only benefit the below average. Likely your shop is small enough that you have little or no dead weight.
