The Department of Labor (DOL) defines a sweatshop as any factory that violates two or more labor laws. Some of those laws pertain to wages and benefits; working hours; and, child labor. The good news is that many municipalities are adopting sweat-free procurement policies and are in favor of transparency over certifications as a means of ensuring ethical practices in the supply chain.
