Answer:
They did not really force management, they forced regulations of the clothing industry, which included better working conditions for employees. This started after the triangle shirtwaist fire. In Theodore's Roosevelt's presidency, he implemented his "Square Deal", which has three C's: Control of corporations, Conservation, and Consumer Protection. The control of corporations part involved an attack on large corporations abusing their power through "trust busting". He enacted the Heburn act, which gave power to the Interstate regulatory commission, which increased regulations upon many large monopolies. He also gave more power to Unions, which helped push for worker's rights. You should also know that since governmental power increased after WWII, large regulation upon industry has been enacted, ever since America came out of the Gilded age. There are more examples in multiple presidencies, but I'm not writing an essay.
