After a quick google, I find that Geoff Martin is from the rmt press office
Assuming that the quote is correct and not something the BBC has made up, I think it proves one of two things:
1) The rmt is so out of touch with things it has no idea about the jobs that it's members do
or
2) It's a deliberate lie just to try and justify something
Either way, how could anybody believe or trust anything the rmt says after that?
In case the BBC page gets changed, I've pasted the relevant section below:
"The RMT (Rail, Maritime and Transport union) reported that managers without a Safety Critical License had been allowed to direct Tubes out of the depot and on to the tracks at Upminster and Stonebridge Park.
It said the situation illustrated TfL was operating with a shortage of staff.
Geoff Martin from the union said: "Seeing the trains out of the depot is an incredibly skilled job. They have an air traffic control system to get them out and it requires years and years of training and certification. They were winging it.
"The strike talks have had to be suspended until we have a satisfactory conclusion on this safety issue."
"The strike action goes ahead regardless," he added
