The annual hike at law firm Quinn Emanuel is part rite-of-passage, part stress test, and not for the faint of heart. Every year, the company flies hundreds of employees to a different location so they can take part in a rather extreme hiking ritual, a kind of company retreat to gather people from far-flung office buildings and build camaraderie. Last month, more than 250 employees flew to Cusco, Peru, to hike part of the Andes mountain range.
