> The best time to unionize is when you're in a strong bargaining position to set a sustainable baseline in your first contract and build the infrastructure to make a strike credible. Unions are strongest when they have a huge fund to support their members through a strike.

I might be wrong, but I don't think the average employee salary would be nearly as high as they are, given unionisation costs quite a lot of money, that drives up the cost per-employee massively. You might say now is the best moment ever to do this, but I don't see why that would be true.
