I have worked for a TMO , about 15 years ago I tempted for one for about 6 months. What struck me at the time was that the tenant board members did have a lot of influence. I've no idea if this was the case at KCTMO ,but at the one I worked for ,a tenant board member interviewed applicants for vacant flats , 100% of them were nominations from the Local Authority, so I would show the flat ,then they were interviewed, and if the board member didn't like them (it was as simple as that) he could turn them down and another applicant was shown the flat.
I did question this with management but they basically shrugged their shoulders
They had to keep the board happy.
I was working in Housing with TMOs started to be created ,a Labour policy sadly. I was against them at the time, because it removed accountability from the councillors even though they were on the management boards.
