Now, some people are saying that double-crewing and changes to St John crewing is the problem. In fact, I agree with the double-crewing changes which mean that emergency workers go out in pairs. We've heard that it's best practice and that it's needed for safety, but it does have implications, and it's a bit complicated when it comes to crewing because you've got paid workers and you've got volunteer workers, and now you've got the requirement for double crews.
