I work for a Victorian government agency and have been on a flexible working arrangement, working part time for the last 10 years. Management are now wanting me to move to me to full time hours because they think it's going to get busier. I have 3 school aged children and have provided 2 medical reports disclosing my diagnosis of anxiety and clinical depression. They are now asking for a psychologist report and if I don't provide one they said I have to move to full time. If I refuse to move to full time (I genuinely can't, my kids only have me and I just can't afford the fees for after school care) can I be terminated?
