Going by my neighbour's experience there is a sure-fire formula: Criticise a nursing home's treatment of a parent. What will then follow is the home's management colluding with the attached social-worker-and-manager to ban you from visiting either of your parents at the home (at £7000 per month). Following on from that, the social worker's manager will put your (different) area's social workers up to contacting your children's school and also visiting you and your spouse to check up on reports that you are a danger to your children.
If you are as lucky as he, your area's social workers will see the truth of the matter and walk away with a promise never to return. But you will have had the dubious pleasure of direct contact with a social worker (why would you want that ?).
You think I made this up - I didn't. It is the very sad truth. But more awful even than the story is the fact that there seems to be absolutely nothing he can do about it (he has looked and tried). Wonderful country, isn't it ? Proud of it, isn't everyone ?
