I guess his people never found out. We didn’t live at the construction site and it was still very early on, I definitely told the foreman/site manager or whatever he is called. Young Polish family men came who really had to work hard. I didn’t know their language but a neighbor spoke Polish. I don’t want to know how little they got paid, even though we paid a market price.
In any case, recognition or a small relief would have been appropriate.
Best regards
