Slavers are everywhere. Just an anecdote from today:
[...]
Okay, I need to explain: In France, when a student has finished his studies, he/she often has to first go through a training period in some company before getting a real job. That is, the student is a graduate, but doesn't yet know the actual job very well, so is supposed to learn it during a 1 to 3 months period working at this company. It means he/she will work, but being still ineffective it is seen as a training course rather than truly working for the company, thus the student is not paid.
The problem is, that many companies use such students needing a training course, to have people who work for free. But in the above case, it was worst than anything I had seen until then. They wanted someone competent, fast, and working a lot, in two different professions, for no salary at all!!
