Re what zebra said, my friend (who had the scaffolding up for a month and a half) had a similar issue. Her husband works shifts and was on nights that week. They came to get the scaffolding at 11am, when he was 4 hours into his sleep. No advance warning. They just turned up!
So that would be like people who work days, being disturbed at 3am, (when they have work the next day,) by a group of 3 men laughing and hollering and talking (loudly,) their loud radio, and the clanking, whacking, and thudding, of the scaffolding been taken down.... for the entire TWO HOURS it took them to do it.
He was absolutely livid and rang the scaffold company to complain. They didn't care though, and said that their men have to do the jobs when they can. 
My friend said a little advance notice would have been nice. If he had known they were coming that day, he would have asked them to come at 8am, and gone to bed at 10am til 4pm or 5pm or so...
Cunts.
As it happened, he was so tired that night, that he had to ring in and say he couldn't make it, losing a night's pay.
Maybe these people who do this kind of shit should have a bit more consideration for others, and the fact that not everyone works between 8am and 6pm!
