The move into EGHQ accelerated the decline, prior to that you could pop in and talk to your managers and for a short time after the move. Then the security desk went in and you were only allowed in to the 3rd Floor managers if you had an appointment.
Good luck getting one of those. What a great way to stop the complaints.
I rang 5 different manager and superintendent numbers last week during normal working hours to get some information. No one answered their phone and despite leaving messages, no one called back. Sums it up I think.
