Tattoos in the workplace are here to stay and may even give job candidates an advantage in competitive labor markets, according to new research from faculty at the University of Miami Business School and the University of Western Australia.

About 20 percent of all American adults and 40 percent of millennials have tattoos, according to the Pew Research Center.
