I read a York University Libraries copy of Mark Fisher’s Capitalist Realism: Is There No Alternative? (Zero Books, 2009). Right near the end he says (pp. 79–80):
New forms of industrial action need to be instituted against managerialism. For instance, in the case of teachers and lecturers, the tactic of strikes (or even of marking bans) should be abandoned, because they only hurt students and members (at the college where I used to work, one-day strikes were pretty much welcomed by management because they saved on the wage bill whilst causing negligible disruption to the college). What is needed is the strategic withdrawal of forms of labour which will only be noticed by management: all of the machineries of self-surveillance that have no effect whatsoever on the delivery of education, but which managerialism could not exist without.
Two different earlier readers had been writing penciled notes in the margins through the book. To the “pretty much welcomed” line, one added:
Then maybe you need bigger strikes! & the ability to negotiate back-to-work protocol that gets you those lost wages! ’Course you’ll still have to cover all the material!
