One of the reasons management 'may' ask SRG (or ATSSD as they now are) to combine T&P, for the night shift ONLY, is that some watches are shooting everyone in the foot. When the senior managers come in on a night (for example DD&C) they see some sectors ROUTINELY work combined T&P, despite it being against MOPS etc. etc. So they have GOT to ask themselves that if the watches think its OK, why should NATS not take advantage and utilise staff who doss down at night to work traffic during the day?
