The 21 Group is a peer-run staff network founded at the University of Cambridge in 2023. It provides a support group and community for academic staff experiencing bullying, harassment, discrimination, or institutional retaliation in their careers. The group describes itself as a network rather than a media organisation, and its work focuses on supporting members and sharing information about workplace issues in academia.

Through its website, The 21 Group publishes articles and updates on Cambridge University matters, including employment practices, institutional reviews, staff treatment, and allegations of misconduct. Its resources include guides on bullying and mental health, as well as information about employment tribunals. The site also provides details about the group, ways to seek support, and employment opportunities. Readers can explore posts by subject, take part in discussions, and follow current and popular stories. By combining peer support with practical guidance and public commentary, The 21 Group aims to help staff navigate challenging workplace experiences and understand relevant processes.
