Journeymen -- the tradition in Europe

Never heard of that as an activity during my lifetime. I know it from litterature, but I tought that ended in the 19th century. Must be something nostalgic. I can't imagine, that years spent in other countries in your apprenticeship or after that would count for a profession.
In Austria, you becomesn apprentice after 15, (9 years of school). It's extremely regulated and hard to change a place. You have weeks of school duties strawn in. Then you pass exams and are a Journeyman. Depending on the trade, you work at this stade for 3 years or so under a master. Then you can pass more exams and set up a shop or you always work as a Journeyman. Ot's jjst an old classification to define levels of competence, rights and salary. Most would just call it Competent worker or Specialised worker or the like.
In France, you start an apprenticeship maybe after finishing school, instead of going to the university. No school duties I believe. Every country has its own system, they would never recognise a year on the road as a year in a shop with a certified master.
There are new traditions forming, like working for your keep, to help or to learn. I had a few guests arriving in Paris for a stay somewhere in France, for farming or renovation of an historic building, and a guest, who offers such stay to young people on an island before the coast.
