I have been promoted twice in the last 3 years, doubling my salary. Honestly, I have walked into the previous role because the manager has left and I (and I thought everyone around) assumed it was temporary appointment until they find a proper replacement. I was way out of my depth but figured it out. The next promotion is the same job but broader geography. I feel like the higher up you get, the easier it becomes. I literally just manage very competent people and small projects, coordinate between departments etc. I am not bored but I feel less useful and competent than when I was grafting for £24k. What is going on - has this happened to anyone else? Should I just chill and accept that this is what career progression looks like? The feedback is OK, but I am massively insecure as I do not feel stressed, if that makes any sense.
