My store lost a bunch of TLs a while back because their jobs just don't exist anymore. Being performanced out isn't the only reason TL and up positions seem to be endangered species. Buuut, I think at this point there's no way they could eliminate another position... Or can they? Idk. And one TL was recently fired and I honestly think her etl was just trying to save herself by placing the blame on the tl.
That said, all my TLs who are still standing have been here for 7+ years. Those who were pushed out were able to find good jobs, and I believe having the tgt TL position on the resume helped.
I have no opinion on what you should do lol. These are just some of the thoughts I had when a TL position opened up at my store.
