I'm fascinated with -
"Lack of commitment to task by some staff (e.g. ATCO 1s often ‘cherry pick’ the parts of their job description that they feel comfortable with and discard the rest – also a tendency to ‘wander’ from their allocated areas)."
I assume that this refers to that multitude of tasks that are "delegated" to the ATCO1s (and others) without allocating them either the appropriate time or the necessary facilities to do the job properly. If they try to do their best, they are "wandering from their allocated areas".
Damned if you do, damned if you don't!!!
