They came to do work in my building. The majority of workers are vulgar and / or aggressive. They insult each other and disrespect the inhabitants. When I asked a worker not to smoke cigarettes in front of my window, in the evening when I got home I found two crushed cigarette butts slipped between the slats of my blinds.

No doubt some are nice, courteous and polite, but I haven't had the chance to meet a single one.

concerning the quality of work, I do not give my opinion because I do not know anything about it.
