Sierra Club clashes with union over layoffs and restructuring plan

Staffers raise concerns about inclusivity and accountability after US environmental organization says it needs to cut costs

The Sierra Club, one of the US's oldest and largest environmental advocacy groups, is going through a turbulent restructuring, which a union has issued two formal complaints about and warned could lead to more than 100 job losses.

Some staff also raised questions about how the changes might affect its recent efforts to improve workplace culture following allegations of misconduct, and boost inclusivity in the aftermath of scrutiny over the racial views of its founder, the conservationist John Muir.
