Leadership doesn't care about their employees. They'll always ask how we can implement new ideas to help streamline our process, but when we give them our ideas that are backed by our peers, leadership always has a response on why its wrong and why they are doing to do it their non-lean way.
Also when deciding on who to make Lead/Supervisor, It doesn't matter if you apply and interview great, they already have people in mind who they're going to offer the job to. So much so that they no longer even post the positions and they'll just offer it to whomever they choose.
