Good post ADIS5000
I work at a Band 5 unit so perhaps my views are slightly biased.
Our place is busy for about 20 hours a day. You get a respite when there is very little traffic between about midnite & 4am. The traffic has increased so much that you cannot tell the difference between a weekday & a weekend.
How many lower banded units can say that they are working to near capacity levels of traffic at 4am? It isn't easy, especially on the 2nd night shift.
I feel that i earn my Band 5 money & as my 4.1% increase of salary works out higher than a band 2 or 3 increase, then i honestly feel that it is justified.
