(see last line for the point)

So, Switzerland is restricting workers entering into the country. Let me wax globally historical about this.

Long time ago:
First we, the common people, were surfs. Bound to land and not permitted to travel to find work. Industrialization had not come about yet.
(The Swiss farmed and traded)

In the recent past:
Industrialization occurred and human rights got the nod as the common people
revolted. A few heads rolled and those that wanted to stay in power became captains of industry and trade. The common people moved to the work in the cities or onwards to colonize. Class/Cast system very strong.
(The Swiss build industry, continued to farm and trade)

Yesterday post World Wars:
Industrial modernization, goods easily moved around the globe. Industry moved, with some cost, to where the resources were best (cheap labor, cheap materials) but restricted mostly because of lack of 'first world' infrastructure in most country's. Us, the common people, could migrate to better prospects with complete ease. 10% of the world population own 85% of the wealth.
(The Swiss build modern industry and get on to Banking and other high order services)

Today, Information age:
Money moves at the speed of light, and in vast amounts (the entire GDP of America and UK combined... A DAY) with incredible amounts of speculation (5% of all that money is considered 'real assets'). Industry is highly mobile and has its pick of large numbers of industrialized countries. Borders are becoming more restricted with Governments restricting the right to migrate to work. Populations of technologically advanced countries rapidly aging. Populations of technologically under developed countries, but industrialized, increasing and wanting to travel to the prior.
(The Swiss focus on high technological and banking services. Restrict access to migrant workers, tend to a social system facing a tipping point,try to address the inequality in wealth).

Tomorrow.. well.. my crystal ball is blurry at the moment
but.. I expect tightening of immigrant workers rights will get worse.
