If a member of the public writes to a councillor, it is deposited in the mail drop. If a member of the public leaves a telephone message, it is written up and left in the councillors mail drop, etc.
Where are these boxes located. In member services which can only be accessed by members of ERC or Councillors.
During the day we are informed that councillors do not attend or spend any time in the lounge, which also has rooms that are allocated to each political party.
Some elected members call once a week and uplift their mail and then leave, others only uplift them when they are at the council for a meeting, once a month.
So your correspondence regarding planning applications, and any other matter is safe and secure from the potential of any 'non elected members' prying eyes.!
