I want to know the answer to the following question:
The first introduction of a quota system mandated that contractors had to do what?
All the background I'm provided with is that "The executive order promoted the idea that if taxpayer funds were accepted through a government contract, then all taxpayers should have an equal opportunity to work through the contractor.:23–4 To enforce this idea, Roosevelt created the Fair Employment Practices Committee (FEPC) with the power to investigate hiring practices by government contractors.:22". Is that enough to answer the question?
Answer: no
