When pension is taken into account a little bit more than I was getting in "Green" (including top rate). It's not all about money. Quality of life or lack of it is what made me decide not to apply to stay when my shelf life arrived. Having the ability to book concert tickets for a date next year etc because I know exactly what I will be doing shift wise and wether I need to apply for holidays to acommodate. (That is what they call them in the civilian world and they are a right, not a priviledge!!)
