how can they interview her for jobs if they have not been in touch?
If she wants medical retirement, she has to be unable to do any work, not just the job she was in prevously. Is there any possibility she could do anything? Has she got brain damage from the aneurysm? can she physically sit? Use a computer? use the phone? If she can do the above she may well be suitable for something else from the same employer. It is notoriously difficult to get medical retiement, and if she does her esa will stop or be reduced.
if she wants to find out what is happening re medical retirement, why dsen't she just get in touch and ask?
