I enjoy my job and have had a good couple of years where I've built my team and delivered really successful projects and generally made good progress for the business. We've taken on extra responsibility and proved ourselves really capable of this.
Alongside my team are more operational functions who have had a more rocky time with changes of management. These functions are now in a stronger position and now want to take on or take back the responsibility that they feel should fall with their remit and they should be the decision maker on.
My problem is that I've structured (recruited), motivated and driven my team to have these responsibilities. It hasn't been easy and we've all worked really hard. It now seems unfair and really a bit of a slap in the face to say 'thanks for sorting that out/building that while we couldn't, we'll have it back now'. This has never been communicated by senior management as the long term plan, it's something that's been raised/demanded by one of the function managers and my feeling is that senior managers are so desperate to make it work after the instability of recent months/years that we'll be seen as collateral damage.
Any advice would be welcome, thank you.
