'I was trained by ATSAs.......will I train an ATCO?????'
Unfortunately, you won't be asked to - they will appoint in-house mentors (same as appeared recently at LL ; 2 from CC and 1 from KK), and the Met Office guys will do the check-out at the end.
For this task, sadly, the question as to whether the station ATSAs will/will not train ATCOs is irrelevent - management will find a way around it.
Anyway, if we did, we'd want paying for it!
