There will be 4 people rostered for each night pairing every night, therefore 20 ATCO's per night on radar duties. If that means that all 4 have to work for part of the night shift at the same time then so be it (been there before), we'll always ensure we stay within hours. On South and West at the start of the shift during the summer this will be the norm, additionally West splits at the end of the shift around 530am. Its not impossible to roster the extra bodies, although I have heard that the north bank may have to re-jig again to get the night validations syncronized to fit all watches. Haven't we been down this road before????
There isn't any problem rostering for DD&C's, only 1 extra ATCO was needed for South and that was always done. The problems came when one of those rostered went sick, trying to find cover short notice is not easy. However the ATSA's struggle sometimes to get their extra bodies needed for a DD&C, but thats not affected by the ATCO change.
