This is a long standing issue.
I remember having to sign papers to say that I was only working 20 hours per week. I reckon that I worked about 60 hours a week - which is also more than maximum hours.
I was happy to do that as were hundreds of other seasonaires. There are, or certainly were queues of people wanting to work in the alps, have a great time, not actually that bothered about pay because passes were given, accom, food, in a protected environment.
Sure it’s illegal but it’s not a job for life but generally a stop gap. Thousands of skiers get good service and cheap holidays on the back of these practices. Tour operators are not making millions out of it so it’s not really exploitative in the sense of fat cats.
This could break some companies and even some resorts! Certainly turn some back into an exclusive domain unaffordable to the masses.
