Also: wage usury under civil law
(Section 138 of the German Civil Code (BGB))
This section operates to render void those contracts that are contra bonos mores (unconscionable). An example of unconscionability is when a person exploits the weakness of another (e. g. someone who is in a dilemma, is inexperienced, or has a weakness of will) in order to create an advantage for himself/herself that is "strikingly incongruous" with what such person is providing in exchange. Wage usury is found when, in these circumstances, an employee is paid a very low wage for the work performed. According to the highest labour court in Germany, wage usury will be found when the employee receives less than 2/3 of the union wage or the customary (standard) wage for his/her work.
