Wikimedia Foundation UK staff seek voluntary union recognition
UK-based Wikimedia staff asked management to recognize their union as more than 1,000 volunteers backed the drive after a team shutdown rattled workers.
Wikimedia Foundation staff in the UK asked management on Wednesday, June 24, 2026, to voluntarily recognize their union, raising a workplace fight inside the nonprofit behind Wikipedia and its sister projects. The employees want to be represented by the United Tech and Allied Workers section of the Communication Workers Union, and union organizers called the effort a global first.
Its projects are the world’s largest free knowledge websites, built and maintained by volunteers. Leadership has publicly affirmed staff rights to organize and form a union, and the recognition request was meant to hold those commitments to account as the organization changes direction. More than 1,000 Wikimedia volunteers and community members have signed petitions backing the workers.
The UK is the foundation’s largest employment base outside the United States, and a substantial majority of UK staff are already union members. John Chadfield, the CWU’s tech national officer, called the move the first attempt by Wikimedia Foundation workers anywhere to seek voluntary recognition. Wiki Workers United is trying to build a durable workplace grounded in transparency, accountability and participation.
On May 20, 2026, Wikimedia Foundation disbanded its Community Tech team, affecting six employees and drawing criticism from parts of the volunteer editor community. The foundation has nearly 650 staff worldwide and is a donor-funded U.S. 501(c)(3) nonprofit. Its 2024-2025 audit showed revenue of $208.6 million, including $189.5 million from donations, and said 77.4% of the budget went to movement support. The same audit marked the foundation’s 20th consecutive clean audit since 2006.
Wiki Workers United is a global solidarity union for Wikimedia Foundation staff and plans to begin with a U.S.-based union structure before expanding internationally, since there is no mechanism for a formal international union with legal protections in the United States.
