Here is a rather funny take on the life of a full-time teacher with all its frustrations: it’s a set of three ‘recipes’ describing typical situations related to food. For example, the teacher was so busy and/or worried and/or hungry that they didn’t have the time for salad which had been waiting for them in the fridge for a week! Sounds familiar? Certainly does to me.
Seriously though, the recipe posters could be put on the staffroom wall or even discussed with students and adapted to their particular jobs. Some people say understanding humour is the biggest sign of language learning!
