Had anyone else had this issue? I've been in three managerial positions, each for a couple of years each, current 2.5 years, moved each time for a pay rise (7k then another 6k), with the promise each time of expansion and line management experience, then it never comes. Every interview hurdle for jobs that require line management experience is my lack of, and the job goes to someone who fills that box. Always 'you were out second best but you just don't have that lm experience we need and someone else does'.
How can I build enough experience without actually line managing anyone? It's so frustrating.
