I just had to translate Lohndumping into English. Not easy! Someone on leo.org suggests using wage dumping plus a definition. It’s true, sometimes a single term needs a single term (one or two words) rather than a long definition, to work in a text. Apparently Lohnunterbietung is a synonym. So the suggestio would be to write ‘”wage dumping” (forcing the reduction of wages and salaries)’ or something like that.

Here are some people on a Swiss forum getting very angry on the subject:

thanks, I’m intrigued by the term itself though. Why use “dumping”? Isn’t the German language capable of describing this practice?

This is kindergarten stuff…

The term is used in English too, usually in inverted commas with a definition. It does usually apply to bringing in foreign workers.
