The windows are coming to change on Wednesday, but I have to be at work. Do you leave the workers alone at home? Or are you standing behind their asses? It is a company with a long tradition. So they could be solid right?
In my experience, the craftsmen - if I don't want to use a more peppery term - can do what I can. I'm not afraid that they will steal or destroy something - but I take care of the quality of their work. I recommend doing it too.
