Ben Jealous, the executive director of the Sierra Club, has officially taken a leave of absence as of Friday afternoon, the organization has confirmed. This announcement follows a tumultuous tenure marked by several layoffs since he assumed the role in 2023. Tensions have escalated within the organization, with local chapters voicing concerns and over 100 employees expressing dissatisfaction with Jealous’s leadership in a letter to the board of directors.

The letter detailed grievances, including a lack of a definitive strategy to combat the Trump administration's rollback of vital environmental protections. Employees accused Jealous of not securing funder trust and claimed the Sierra Club has been experiencing a "downward spiral." In a statement, a spokesperson for the Sierra Club declined to address specific personnel issues or the reasons for Jealous’s leave. Meanwhile, Loren Blackford has stepped in as interim executive director, aiming to stabilize the organization during this critical period.
