Before entering Schengen, Switzerland was a very closed country for the job market. It was very difficult to get a permit. Switzerland had (has) a major issue: salaries were high compared internationally and there could not import skilled employees. So all the companies/factories had trainings to keep their employees and "transition" them when the technology or business was changing and making their CV obsolete. The companies with the best training/programs were attracting talents. So all companies had to do it. Otherwise they would not attract talents. It already starts with apprenticeship. Did you know that you could start a top career in a top Swiss bank with an apprenticeship at 16 yo? Some companies are still like this. But most of campanies prefer now to simply fire and hire an already baked employee; but they keep training programms made by HR more for marketing/communication purposes than a real culture.
