Further, women and minorities also tend to receive fewer training and mentorship opportunities, and the unsteady flow of work in construction often impacts them the hardest because they frequently lack of social support structures, according to the report.<br />Despite the challenges involved, Thompson and others who crafted the study are hopeful that efforts now under way will lead to meaningful changes.<br />"There are all kinds of things that give me hope," she said.
