Many of us dream about the moment when we get that longed-for promotion. Imagine that it’s yours: a great step up the career ladder, huge responsibility, a bigger team and a whopping pay rise. It all happens so quickly: your predecessor gives you a fast handover, you meet your new team and peers, and your boss sets your objectives for the year. After a whirlwind few days, you walk into your new corner office (if you are really lucky), sit behind your new desk and savour your success.
