moving up to manager but the other staff are more trained than me/ always in charge
So past two months I was informed that I was getting moved up to manager which I agreed too. I was told roughly when my training would start., expect most of the staff in my work seem to have more training than me. At first i was like "whatever it doesn't matter" but now I'm like how come half the staff are trained in things I'm not even trained in yet but I'm the one moving up? I don't understand? Not just this but I always have at least one member of staff in charge over me, which is bizarre because I'm th on who's moving up. Obviously Im not manger yet which I understand but why are other staff being trained in things I need to b trained in and why are they the one in charge of me.
How will I ever be manager when sales assistants are tellin me what do(bossing me around) and they have more management training than me. I was told my training would start this week but I've had zero training yet and I'm still dealing with everyone else in charge of me?
