Surveys by the independent transport watchdog London TravelWatch have consistently revealed that, despite LU's spin that closing ticket offices would make staff "more visible", passengers consistently have difficulty finding members of staff to assist them on stations.
Here at Tubeworker, we think the problem is clear: there aren't enough staff. The solution is to reverse job cuts.
LU has other ideas. It insists the problem is one of "visibility", and to ameliorate this it is trialling the use of red tabards (emblazoned with "here to help") at certain locations.
