I work in a French administration. We have a special day, the "journée des nouveaux arrivants" ("newcomers' day") for new hires, where we are taught the history of the service and learn about the different departments. The only problem is, since there are few new hires and organizing it requires the animators to be here, that this event takes place about twice a year.

I was lucky, my manager thought about it and managed to get me to do it after a bit less than a year. Some people have been working here for years without the "new hire day" (in all fairness you don't learn a lot of practical things, but still...).
