Apologies tiggerific_69, I thought when I first read your post that you had added this last sentence "Only on Pprune could a 20% increase in pay be called a pay reduction" yourself but having looked at it again I realised you hadn't. In my defence it was late (relative to the time I got up that morning anyway) and the end of another long week at the coal face!
Apologies once again.
Shame on me!
