Tube station Supervisor in London (TfL). Once you start on the Tube, it's rare to move on because the money is good and the benefits are fantastic. You start as an assistant grade 2 with the opportunity to get training to grade one after a six month probationary period. Then you are put on a list and you move to your new station. After a year, if there are vacancies, you can apply for my job, a grade two supervisor than manages more suburban stations then after another year you can apply to grade one where you manage a zone 1 big station like Bond Street. Then up to management. The waiting lists for promotions take years though.
Day to day, it's helping passengers find their way, handling money from the ticket machines, platform train interface duties (making announcements, dispatching trains), assisting sick customers and unfortunately, helping with persons under trains. I've had one suicide on my watch in 20 years, so it's rare. You also help your team members around the station, and assist train operators and line controllers. You also go down to the track to fix points and other bits and bobs.
Most days are the same, but sometimes customers surprise you, sometimes something happens that isn't in the rule book, and you have to think on your feet. All the controllers care about is their trains are running so you have to act quickly or they are harassing you to get the service going again.
Apart from some internal politics and some misogyny I like my job. Some of my colleagues are good friends. We have all types of people join, from retail, theatre, journalism, local government, we even employed a former thrash metal singer once. One of my friends used to work in cyber-security. So as long as you are judged to be customer focused and are sensible you are in with a shot.
