To quote the meerkat Alexander, simples, that’s how to solve this situation. The scaffolders shouldn’t have done what they did, their employers should have reprimanded them for it, and they should have apologised to the women in question, and reassured her that if anything like this happens again by the same people, then further disciplinary actions will be taken.
Now, just what exactly would you like to have seen done to these scaffolders as punishment? A formal warning? Getting fired? A public flogging in the town centre maybe, or should we just have a good old fashioned hanging?
The scaffolders were in the wrong, they should be told that and punished accordingly. The woman involved may have been hurt or upset and maybe pist off that this happened, but the good thing is that it’s a rare thing nowadays for it to happen.
