Next thing you know, you'll have non ATSA staff coming in from Projects and the like to do the ATSA job because management cocked up by letting ATSAs go before EFD was fully operational
Be expensive on T&RE bringing up non PC staff.
maybe the canteen chef, the receptionists, and the cleaners, could get a quick ATSA 'validation' and help out too ?
Previously ATSA posts have been filled by contractors responding to jobcentre vacancies, if you've got the necessary aptitude anyone can be trained.
My earlier response to your post was my own humble opinion <shrugs>
