Working on change provides a fascinating glimpse into the opportunity that climate change provides for modern trade unionism, and the prize that lies within all of our reach. The contributions to this pamphlet by Jack Dromey (Unite) and Sally Hunt (UCU), by Paul Noon (Prospect) and by John Sauven (Greenpeace) all tackle this head on. They highlight the scale of the manufacturing and employment opportunities in the transition to the low carbon economy but also focus on the pressing need to ensure that we realise these opportunities.
