Drivers have criticised Transport for London for allowing scenes to be filmed on the Tube network and for allowing posters to be put up in stations, some close to the sites of suicides. Steve Grant, a district organiser for Aslef and a former Tube driver who has experienced three people jumping under his trains , said: "Some people take it as part of the job, some people can't cope mentally. Drivers suffered flashbacks, sweats, and were unable to do their jobs. We don't find the subject humorous at all."
