Dr. Shannon Joslin, a non-binary biologist at Yosemite, was fired after helping hang a transgender pride flag on El Capitan, sparking debate over free speech and workplace rights.

Among the climbers who helped hang the transgender flag was Pattie Gonia, an environmentalist and drag queen who uses the performance art to raise awareness of conservation issues. For the past five years, Gonia has helped throw a Pride event in Yosemite for park employees.

A former Yosemite employee says they've been fired by the National Park Service, three months after flying a transgender pride flag from El Capitan.
