In case you hadn’t heard, the teaching profession is in the middle of a recruitment crisis. So with trainee teachers becoming a bit thin on the ground, you’d be better off being nice to the few that you have. Here are five things it might be better to avoid saying say to them: 

1. “Oh, sorry, I thought you were a senior” 
   Being accused of being youthful is a compliment in a liqour store. In the staffroom, it’s just an embarrassing reminder that the trainee teacher still has a long way to go to attain the appropriate level of world-weariness required for the job.
   
   
   
   
    
2. “This will count as good evidence for your files” 
   Don’t mention the files. There are five of them. They are overflowing. Hulk Hogan couldn’t lift them. 
   
   
   
   
    
3. “Right, let’s discuss differentiation/independent learning/lesson outcomes” 
   You may think this would be helpful, it is not. Chances are the trainee teacher has discussed these things more times that you’ve told a student to tuck in their shirt in the past few months. Yet another lecture on the numerous benefits of using de Bono’s thinking hats is about as appealing as a trip to the school canteen.
   
   
   
   
    
4. “Take this worksheet to Mrs Smith in reprographics to be duplexed” 
   Who is Mrs Smith? Where is reprographics? And what, in the name of Donald Trump, is duplexing?
   
   
   
   
    
5. “It might help if you got to the classroom five minutes early” 
   Ha! As the bottom of the educational food chain, the trainee teacher is only ever given classrooms that couldn’t be further apart. Not even Usain Bolt in a Bugatti Veyron could make it from one side of the school to the other in time for the start of Period 2. Especially not with a tray of pens and an armful of exercise books to boot.
