Hello everyone. I have taken a break from teaching whilst travelling for a year. I successfully applied for a new job whilst abroad (via Skype) containing former colleagues at a new school which was an easier process. I was told that I wouldn't be paid for the summer but that I would get a week of supply work if I came back before the summer holidays. I returned and met my new class for the day yet was told not to come in again as previously promised. Do I have a leg to stand on with regards to unions etc? I am missing out on much needed verbally agreed supply days and I don't know how to proceed. Thank you in advance.
