The giveaway word in all this is TUPE. While it’s a fine idea in principle it means the new organisation has to take the deadbeats along with the good uns. Which means that usually the people who weren’t up to running and/or doing the job in the first place are the very same people who will be tasked with doing it still.
Sure, some new management might come along, but it’s very difficult to change a culture that’s been in place for a while (and I’m speaking from personal experience).
