The University of Washington Tacoma Staff Association (UWTSA) facilitates communication among UW Tacoma classified and professional staff and librarians and between staff, faculty and administrators on campus-wide issues. The UWTSA also seeks to unify staff at UW Tacoma to enhance the working experiences and ability of staff to contribute to the larger campus community.

The UWTSA does not deal directly with personnel issues specific to individuals or individual job categories represented by other professional organizations.The UWTSA is officially recognized by UW Tacoma but is self-supporting and does not receive funding from the university.

All UW Tacoma staff members, including non-academic directors, are automatically members of the UWT Staff Association. There are no membership dues and participation is voluntary. Information about UWTSA activities is sent out via email.
