First, can I make it clear I am not complaining!? Just baffled! So today I had a one-day job teaching Y5/6. I'd just sent the registers back to the office and was just about to get going with the first lesson when... the Y3/4 teacher rushed in, apologising that she'd forgotten to mention earlier that the children would be rehearsing for their end-of-year production. The rehearsals went on until morning play. Then resumed until lunch. Then resumed after lunch. They went on all day. ALL DAY! The children did NOTHING else! Why would you get a supply teacher to come in just to take two registers and then pack the kids off to the hall? It was amazing!
