Nanatoone, I was off for a year from my teaching job, due to multiple.e comorbidities.
My HT got in THREE supply teachers to cover my job.
I can assure you that the L.A and DWP are very robust in their practices. I had a number of medicals and interviews, because I had eventually run of out of pay. No-one accused me of malingering or being a flake.
The clinicians, who examined me were horrified at the number of hours I was working and agreed my workload had contributed to my failing health.
I had to stop working at 59, no state pension and two young for my teacher's pension.
I certainly wanted to keep working.
Thank goodness, your daughter wasn't one of my colleagues, who were so supportive.
