Presentation slides from seminar at TUC 23 January 2012 'A positive agenda for disability and employment'. A video of Kaliya Franklin's presentation can be seen here http://www.youtube.com/watch?v=wh4MMnLUzkc&feature=youtu.be
The slides consist of charts and bullet points organised around five types of bias in discussion of disability and employment, and of social security more generally: stasis, homogeneity, dependency, scale and insularity. That list doesn't claim to be comprehensive of course.
[Note: I've just noticed the first chart is mislabelled, 'disabled' for 'non-disabled'. I'll fix this as soons as I get a chance.]
