Sick-in
Summary
A sick-in is a coordinated mass sick-leave action in which workers or students collectively call in sick on the same day to disrupt an institution. In Sharp’s 198 Methods taxonomy it is method 112 — listed as “Reporting ‘sick’ (sick-in)” under The Strike — Restricted Strikes [source: commons-198-methods].
Body
A sick-in is a restricted-strike variant: rather than walking out (and being counted absent) the participants stay home with reported illness, so the institution must decide whether to discipline what looks like a mass health event or to absorb the disruption [source: commons-198-methods]. The tactic’s force depends on plausibility (the absence must be medically defensible per participant) and coordination (the same day, the same workplace, often the same department). It is most effective in institutions with hard-to-replace roles — care work, teaching, transit — where the work cannot be contracted out for a day. The political effect is the institution’s response: does it call it a strike (and concede the collective action) or treat it as genuine illness (and absorb the cost)?

FAQ
What is a sick-in?
A sick-in is a coordinated mass sick-leave action in which workers or students collectively call in sick on the same day to disrupt an institution. In Sharp’s 198 Methods taxonomy it is method 112, listed as Reporting ‘sick’ (sick-in) under The Strike — Restricted Strikes [source: commons-198-methods]. It is a restricted-strike variant: rather than walking out, the participants stay home with reported illness, so the institution must decide whether to treat it as a mass health event or absorb the loss.
What makes a sick-in effective?
The tactic’s force depends on plausibility (the absence must be medically defensible per participant) and coordination (the same day, the same workplace, often the same department). It is most effective in institutions with hard-to-replace roles — care work, teaching, transit — where the work cannot be contracted out for a day. The political effect is the institution’s response: does it call it a strike (and concede the collective action) or treat it as genuine illness (and absorb the cost)?
Where does the tactic sit in the Sharp taxonomy?
The sick-in is method 112 under The Strike — Restricted Strikes in the Sharp taxonomy. It sits within the broader economic noncooperation category, where the worker withholds labour but in a bounded, deniable form. The advantage over an open walkout is that participants cannot be cleanly disciplined as strikers; the disadvantage is that the action is harder to communicate and harder to repeat.
What historical examples illustrate the method?
Two worked examples anchor the tactic. The 2002 Central African Republic teachers’ strike over salary arrears is a worked example of large-scale withholding-of-labour in the public-services category where a sick-in is one of the restricted-strike variants available. The 2013 Chicago students’ and teachers’ mass action around school closings is an example of public-education labour withdrawal.
