mails asking for VR applications were sent to targetted groups. The ones identified in our meeting, which I think was the same one that Radarspod went to, were Swanwick ATSAs, Asset Engineering, Programmes, Engineering Service Delivery H24 and Technical Services which includes Operational Research and Quality Assurance. Seems to be about 10% in most of those groups although the exact numbers were restricted to each e-mail so nobody can easily work out how many in total.
I think you mean
Technical and Scientific Services of which I believe Operational Analysis, Asset Engineering and Quality Assurance are part (although P. Baron's recent news article makes the T&SS division redundant).
The powers that be are looking for Operational Analysis to lose 7 people (10%) although I think they only recently got reduced by 10%...so I guess that's really 20%.
Not sure how many QA and AE, but I believe this is also supposed to be about 10%. Interestingly Operational Analysis are generally speaking on STAR grades which are some of the lowest in the organisation.
