A rail union has hit out at a “cynical and shocking stunt” after a train company emailed staff to promise a bonus to workers who had run trains during the pandemic – only to reveal it was in fact a test of their cybersecurity awareness. West Midlands Trains emailed about 2,500 employees with a message saying its managing director, Julian Edwards, wanted to thank them for their hard work over the past year under Covid-19. The email said they would get a one-off payment as a thank you after “huge strain was placed upon a large number of our workforce”.
