I’ve been in my current role for 2.5 years, which was a promotion from a similar role I’d been in for 7 years prior. I’ve got nice colleagues, an approachable manager, flexibility, pay is fine for what I’m doing, I don’t hate my job and find it only minimally stressful although there have been some changes in the past year which have made it much harder. I think this combined with my youngest having gone to school last September is making me think I would like to branch out and have a better paid role with more responsibility. I’ve seen a job I fancy going for but now I’m doubting myself. I’m well qualified and have some but possibly not all of the experience they’re asking for. It’s a jump in salary from around £40k to around £54k, is that ridiculous?
