TSSA is the biggest trade union in Transport for London. We represent staff in TfL offices and stations, bus operations, London Underground, TfL Rail, overground and anywhere the TfL network extends to. We actively engage with our members, holding weekly meetings and engaging extensively with the business.

We represent everyone from apprentices to senior managers. We are the only union with recognition in all parts of the business, including recognition for collective bargaining on pay and key industrial issues, including Equality, Diversity and Inclusion (ED&I). We're also the only union that is recognised for collective consultation on behalf of senior managers.
