We used to have that attitude from construction workers over here about 40 years ago.
Thankfully it has changed and now they get taken to court and fined or even jailed. Also the company they work for get fined too
The worker will lose his job, and the company will lose work because of the bad press.
Speak to your Dad, he's the one paying them, if he threatens to discontinue the contract and get another company to
finish the job, perhaps they may stop.
As for the noise and Music, well. . . you'd hear that even if the door was in place.
