My husband and I adopted a child last year and I took one year of adoption leave from my job as Head of Spanish in a high school.
While I was on leave, the person employed to cover me was made permanent due to other staff in the department leaving. I only found out about this after it had happened.
I returned at the end of December, temporarily working 3 days per week until August and then I will be working 4 days per week. I agreed that the new person would continue in my role until the end of the academic year, but made clear that I wanted to return to my role in September. I have recently been told that will not be happening, but have been offered another role (same pay and conditions, but not a job I want).
From what I understand, I am entitled to return to my role unless there is a good business reason. Is the fact that they made this employee permanent while I was on adoption leave considered a good business reason? Has me agreeing for them to do it temporarily while I am working 3 days per week damaged my argument? Is there potentially discrimination on the grounds of sexual orientation, as this would never have happened if I hadn't taken adoption leave?
