Why did unionization result from immigration and migration concerning the coal industry?

Question

I have been up for 24 hours and need help. Please help by making this concept easier for me to put into words for my essay due tonight.

This is the last part of my essay I am working on:

Show how the elements: immigration, migration, transportation, unionization of industrialization were manifested in the coal mining industry in general.

Answer 1

It doesn't sound like they actually want to know how unionization resulted from immigration and migration. They just want to know how unionization of industrialization was a part of coal mining. Just show what part unionization played in coal mining, the effects, why it happened, etc.
