Construction often ends up with the worst sorts of people. I have multiple friends and family who have worked in the business and they’ve dealt with people who would regularly no-show (not even call in sick), show up drunk, high on meth, and do all kinds of dangerous / stupid stuff including throwing heavy tools down from upper floors, walking around without paying attention (and falling off scaffolding etc).

My uncle also had to deal with mafia guys involved with construction unions.
