Higher Education is one of the most casualised employment sectors, with many colleagues in precarious jobs for many years, postgraduate students being exploited in teaching roles, and other examples.
At Queen Mary estimates about the amount of work done by casualised staff is about 75%. Management dispute that exact figure but do not dispute the overall situation.
In the Spring strike of 2018 there was a teach-out on casualisation - notes
Nationally the UCU has had campaigns about casualisation under the slogan Stamp out casual contracts although there is criticism that they have not done enough on the issue.
There are a number of people and groups active on social media
