Not long ago, the Bureau of Land Management, an agency within the U.S. Department of the Interior, began distributing “vision cards” to its employees. The front of each card features the B.L.M. logo (a river winding into green foothills); short descriptions of the Bureau’s “vision,” “mission,” and “values”; and an oil rig. On the flip side is a list of “guiding principles,” accompanied by an image of two cowboys riding across a golden plain. Amber Cargile, a B.L.M. spokeswoman, told me that the new cards are meant to reflect the agency’s “multiple-use mission on working landscapes across the West, which includes grazing, energy, timber, mining, recreation, and many other programs.” Individual employees, she added, can opt to wear or display the cards at their own discretion. But, according to the advocacy group Public Employees for Environmental Responsibility, which obtained photos of the cards and shared them with the Washington Post, supervisors in at least two B.L.M. field offices have been verbally “advising that employees must clip them to their lanyards.” Some workers, speaking to the Postanonymously, said that they felt they had no choice but to comply.
