Question

Which of the following groups frequently protested the hiring of unskilled factory workers in the 1800s?

craft guilds
labor unions
Pinkertons
trade unions

Answer 1

I believe the answer is: Trade Unions

.

The hiring of unskilled workers was being done by factories to cut down the labour expense that they have to pay in order to obtain more profit. This lead to situation where a lot of skilled labors become unemployed, which cause the massive protest from the trade union.

Answer 2

It was the "trade unions" that frequently protested the hiring of unskilled factory workers in the 1800s, since almost all the members of the trade unions were skilled workers who didn't want their jobs taken away.
