This is a hypothetical question at the moment, but a part time temporary nanny I have recently employed as suggested going on a payment scheme which suggests she may be currently on some kind of incapacity benefit (this could be wrong though). I have a feeling she has a mild learning disability which is fine, but it could be something more. My son has a moderate learning disability too so I am all up for equal opportunities. But my question is, if a nanny has a condition that is severe enough to be on a benefit e.g a mental health problem , then could you realistically have them employed in a sole charge capacity of 3 under 5 year olds (not all at once). The literature online seems to suggest you can't discriminate and nor does an employee have to disclose their condition, but there are limits surely?
