Oh, that issue is even more complicated. For one thing, Switzerland isn't in the EU, but they benefit and depend more than they'd like to admit from trading with the EU and from highly skilled immigrants they don't have to pay to educate. So they do have certain treaties about free trade, and mobility of workers is an important condition in these treaties. In breaking the treaty, there will be at least some consequences. Also, the opinion about immigrants in Switzerland seems to be very complicated. People seem to both feel "We have to much immigration", but they don't want to get rid of the immigrants they know and depend on. For that matter, they think there are too many Germans in Switzerland, on the other hand their economy extremely depends on those immigrants. The government will be hard pressed to find enough immigrants they can get rid of without serious consequences and even antagonizing those voters who voted for the restrictions in the first place.
