My year team colleague is striking. I don't mind exactly, but am a little bothered by the practicalities as school will be open. Literacy, PSHCE and PPA is easy for me to organise for my own class. However we set for maths. Do I ask those in my maths set, but not in my class, to come in for the hour as there is no reason for them not to? What happens to those in my class who are in the other maths set? Do they go home for an hour mid morning? In theory no-one can cover my colleague's class, but then again we can't have children to-ing and fro-ing to and from school can we?
