I don’t normally post on education threads but this one is of interest.
I work in a large secondary with around 100 teaching staff. Some arrive just in time and leave on the bell, this does annoy me. The majority don’t do this.
Personally I leave the house before 7am and have a 10-15min drive to work. I work from the moment I get into school, through lunch time and normally get home well after 6. 7pm has become the norm. I am on the SLT so don’t have as much planning as others, my partner teaches more classes than I currently have and spends at least 5-6 hours on a weekend planning/marking/prep.
Our school has just moved to a new build. During the summer I had one day off and worked two of the weekends to ensure that the move was successful. I don’t know how much harder I could work.
