Hi lizw,
I am in the building trade, and must admit our language can be a bit strong, but you should not have to put up with this sort of behaviour on a site that is occupied, go to the site office and ask to see the site manager or the clerk of works,tell him exactly what is happening,this should sort it, if not, speak to one of the executives of the main contractors, hope you get it sorted,do it today, good luck, Ray
PS that particular word you mention,is the most offensive word I know and i never use it,it makes me cringe .
