Why did labor unions develop during the Industrial Revolution?

During the Industrial Revolution, some Business Owners were taking advantage of workers, with low wages, long hours and unsafe working conditions. When a worker approached anyone about these conditions, they were fired or told to take it or leave it, leaving them with no choice but to work through the harsh environment in order to make a living for themselves or their families Labor Unions were developed to give the workers a voice in the work place. It set up specific laws and rules that the Business Owners had to abide by or face penalties.It gave workers a way to speak out about unfairness, unsafe environments, and gave them rights such as time off, sick pay and retirement plans.
