TUCSON, Ariz.— The Center for Biological Diversity and the Workers for Biological Diversity today announced the ratification of a collective bargaining agreement. The agreement, codifies many Center policies and benefits, increases traditional raises and paid time off, enhances consistency and transparency, and upholds the organization’s longstanding commitment to equity and diversity.

“We’ve worked hard together to reach this milestone, and I’m grateful we’ve found common ground on an agreement that affirms what’s best about the Center and respects the best interests of everyone here,” said Kierán Suckling, the Center’s executive director. “With great care and appreciation for each other, we continue moving forward as a just, equitable organization full of people determined to save life on Earth.”

“This contract is a monumental win for workers at the Center and will make our organization an even stronger advocate for threatened communities, wildlife and wild places,” said the Workers for Biological Diversity Bargaining Committee. “We continue to stand in solidarity with the broader labor movement that works to protect people and places against big polluters and other powerful for-profit interests.”
