ATMD CAD,
Maybe the Check controller,LCE, whatever it's called should sit in with her,and keep an eye on the situation.HK weren't good at continuous monitoring of standards.Perhaps part-time working would be a solution from your caring sharing management.
As far as recruitment,then what was the advert in Flight about? It appeared a few months back,for a few days,and wanted radar controllers under 40.
Recruited via an external agency? It also broke their own age discrimination policy.
So does the localisation policy still exist?
