How can we find out how many organisations actually use them here in the UK (or even just England) ?
I’d be willing to bet that none who receive any kind of public funding do, out of fear of repercussions.
I only know of Freedom programme and the Womens Holiday place who use the exemptions, they can resist pressure because they have no public money. I do hope there are more - if there are public bodies who do, so much the better.
