Before you start thinking of redundancy or anything else do a quick calculation -
1. How many ATCOs needed for current MACC operation ?
2. How many ATCOs actually there ?
3. How long to train replacements for either one above to give each ATCO the same number of validations now held ?
The probable answer is you needed to start training 3 years ago to let anyone go anywhere else other than Prestwick.
