Excellent - accepting 'menial' work can lead to excellent experience and show your skills, rise up internally with training in management, etc, gives you good references, something neither a CV nor a letter can do.
Unemployment in CH is around 3% and rising - as tourism is in trouble due to high Swiss Franc, and so is export of our precision engineering and other products. The high Swiss franc is a disaster for your average Swiss. But there are huge difference from area to area. Zurich, Zug and Geneva have high umployment- but my area of the Jura has 10%, with 10000s of cross-border workers coming to work here every day.
My dad had to break the stones for the sidings with a pick axe - despite being 24 he was very fit and strong, and never fitter nor stronger by the time he retired! Of course if he had not been so fit, he would have been offered other work, and if none, just collected his unemployment benefit until he retired at 65.
After the unemployment benefits of 18 months is over, people are helped by their local social services, but at the lowest of the low survival rate, which, as said, is very tough, but ensures that people do not sit back collecting benefits- but have to continue to train, apply for jobs, if necessary 'below their previous expectations'. Nobody here can earn more on the 'social' than in work.
