I always thought it would be the opposite. If I was hiring someone and going to the expense of that whole process I would not hire someone I thought would be constantly looking to jump ship at the first opportunity.
Funnily enough, I was just offered promotion on Friday. This is less than two months after I started another job they gave me last year after making me permanent. If I had known this would come up so soon I would never have bothered a accepting the first job at my current banding. Manager is going to be pissed as they are already short handed and the health trust HR are useless strawberry floaters who take half a year to fill a vacancy. Oh, well, got to look out for number one I suppose.
