I am a secondary teacher currently on maternity leave. I requested to go back part time, but was turned down. Fortuitously, a part time job in my subject has come up at another local school, so I'm applying and rather desperate to be successful! However, I'm struggling to explain in my letter why I want the job. It is a step down because I will lose my TLR. I've only ever written letters that outline my ambition and desire for progression. Is it okay to say that I'm attracted to the job because it is part time, or should I try to come up with some other reasons? How can I phrase it?
