I used to have a slave-driving, penny-pinching boss would would probably LUV a sign like that! LOL.
I worked for that guy! We put a sign over our shop that said “Works Makes You Free” (in English). He saw it and was so impressed that we had “finally gotten with the program”. It stayed there for 2 weeks before some other manager who was more historically savvy pointed out what it really meant and he made us take it down.
