"This past January, twenty-seven year old Ryan Hiller died when a tree fell on his tent cabin during a storm at Yosemite National Park. Tent cabins are structures with concrete flooring and walls, canvas roofs, beds, a dresser, but no cooking or toilet facilities. They are meant for overnight visitors who don’t want to pitch tents or stay in an expensive Yosemite lodge. Ryan wasn’t camping, however. He was a seasonal employee of the Delaware North Corporation, which manages the concessions at Yosemite. Tent cabins were the company housing the corporation provided, and for which Ryan had to pay rent.
Millions of people visit our national parks every year. They stay in hotels, cabins, and campgrounds, eat in the restaurants, and go on various excursions. You might be one of these persons. Did you ever wonder about the workers who checked you into your room, served your meals, or drove your tour bus? How much did they get paid? What were their working conditions? Where did these men and women live?
The federal government contracts national park concessions to private corporations. Three prominent concessionaires are Xanterra, owned by billionaire Philip Anschutz; the Delaware North Corporation; and Aramark, the global food and services provider. Park concessionaires collectively now have gross annual revenues of more than one billion dollars!
These businesses build their profits on the backs of some 25,000 workers, most of them hired seasonally." . . .
