Old and Horrified:
It *is* a great position to be in if there is limited initial work available. But the newly inked CPL(H) needs to make sure that the work offered is a) well within their experience constraints, b) there's a valid and rigorous supervisory regime and c) that they investigate any insurance requirements and agreements in place before they take up offers of such work.
If not, that newly qualified CPL(H) will have a higher likelihood of ending up in a place where they shouldn't be with their limited hours.
