What organization did workers form in the mid-to-late 1800s to improve pay and working conditions

In the late 1800s, many workers got together to organize what we now know as unions. Those Unions were meant to solve their problems related to working conditions. Some of those problems were: low wages and unsafe working conditions, for example. At first, the workers created local unions in single factories. Eventually, those unions used strikes to try compel employers to raise their wages and/or make working conditions safer.

from my own personal expirence food stamps has alot this makes it eaiser so we can affod bills and so we can life a better lifestyle not needing to worry about paying actual money to buy food since most people spend 100-300 dollars a month on food so this alot so we can afford other bills and other stuff we need
