> If you form a union and then the company goes bankrupt...

And we've come full circle to the bogeyman again. Before we get caught in a loop I'll reference historical record of positive outcomes actually happened, and I'll sign off from this circular debate.

What if you form a union, and with other unions force employers to accept a 5-day working week, instead of 6 or 7 days per week? Or striking until 8-hour work days are the norm instead of 12 or 14. What if you fight employers for decades to end child labor amd ultimately succeed? All these things are examples of actual changes effected by pressure from organized labor to improve the lot of workers. It wasn't "free markets" competing for labor. Perfect competition doesn't exist on planet Earth, especially for labor.
