General Union of Trades in 1818 in Manchester was the first Union formed in Manchester.
Explanation:
The first union that was formed was the General Union of Trades, which was founded in 1818 in Manchester. Workers organized unions to solve their problems in the late 1800s. Their main problems were low wages and unsafe working conditions that affect their health as well as financial conditions. At first, the workers formed local unions and after sometime, they also formed national unions. These unions used strikes as a tool to force the owners of the industries to increase wages and make working conditions safer for the workers in order to avoid damages at the working site.
