mainecoon,
You are missing the point that the proposal is that the WHOLE watch starts at 0630. Like you we already have spins that start as early as 0600 but this is a major change from that situation.
It is a fact that local WP deals are never linked to pay but true that if there is anything in the re-structure then this is the type of flexibility which may affect how a unit gets paid.
You're right that we do get paid more and if it was up to me the differentials would be greatly increased for LACC/LHR and LTCC in order to attract and retain more people to these units. After all we never hear about retention and recruiting issues at the likes of MACC do we??
