When the Gatwick SMVCR was built airside in the 1980s, staff were inconvenienced - their travel time to work increased. Did they bleat on about it ad nauseum? No. Did they expect remuneration for it? No. Did they accept that this was inevitable change, face the front and just get on with it? Yes.
When the Gatwick SMVCR was surrounded by concrete in the 1990s, staff were further inconvenienced - their travel time to work increased again. Did they bleat on about it ad nauseum? No. Did they expect remuneration for it? No. Did they accept that this was inevitable change, face the front and just get on with it? Yes.
Ignoring for a moment the argy-bargy surrounding EFPS (separate issue), I'd be grateful to know why Heathrow staff faced with a move to the NVCR feel that they should expect special treatment when their colleagues at Gatwick faced with similar circumstances got cock-all - twice.
