''Maybe people need to step back and 'regroup' from time to time''
This describes exactly what is often needed, but there is never time to do just that. Furthermore it is often seen as a weakness.
In my opinion, the more experienced one gets, the more one recognises the need to take a step back in order to come forward from a fresh objective standpoint.
Unfortunately the newly qualified/inexperienced workers are often left to drown and then blamed for mistakes they make.
