UNISON exemplifies the role and work of a modern trade union. It protects its own members who deliver public services, and looks to ensure that all are treated fairly. It also runs campaigns to raise awareness and influence government. It campaigns both nationally and locally.
Locally, it works for individuals or groups, gaining for them better working conditions or compensation for unfair treatment. Nationally, it has encouraged many improvements, which either have become law or are in the process of doing so.
