You don’t bother to get to know the new teacher (or even learn their name) until they’ve worked at least three months (or pass probation, whichever is later).
You project a world weary cynicism to all that encounter you in an attempt to stop any stupid questions coming your way.
You’ve given up being nice to the local staff in your school and instead just bark orders at them.
You’ve given up lesson planning - you just re-use lesson plans from three years ago. If at all.
You can’t remember the last time you tried a new activity in the classroom.
Lessons, days, weeks, months blur together. Hang on, it’s August? 2018?!
You get overly irritated at any change to your schedule – it means you actually have to think and alter months’ old personal routines.
You arrive at school and leave within a minute of your scheduled hours.
You dread all extra-curricular activities and student parties. Except for Halloween, where you take an unholy childish delight in scaring all the young learners so much that they cry.
Your manager has stopped assigning you as a mentor to new teachers – they all seemed to break contract and leave early…
You have an encyclopaedic knowledge of grammar and teaching methodology – but can’t be bothered to use it, or answer your newer colleagues’ questions.
You have extra copies of flashcards and materials that you made yourself (but refuse to lend to anyone else).
In holidays, you don’t bother travelling but just stay at home and watch movies and/or play computer games.
Are there any more that I’ve missed?
