One site I worked in had this problem – due to ethnic cultures etc.
Also they we had signs for not urinating in the sinks.
I’ve worked on a site where the English painters had a habit of peeing down the sinks/wash basin ’cause they were too lazy to walk to the bogs. Unconnected to the water supply, and during the summer months, the trapped piss in the u bends started to seriously stink after a couple of days.
This week at the site I’m working on someone peed right against the main entrance of the block being built, the yellow piss-holes in the pure white snow where quite unmistakable. The prime suspect was the very english mouthy plumber.
Many years ago I was working on a site doing studwork, I had loaded the unit out with timber and had the drawings laid out on the floor ready to go, when I realised I didn’t have any nails. I was gone for 10 minutes at the most, when I returned someone had had a dump in the corner and used my drawings to wipe their arse – I kid you not. The only people working nearby were the brickies – all english as I recall.
I could go on, but suffice to say that building workers, whatever their cultural origins, tend to be disgusting and only semi-civilised. Which at least lets me off the hook when it comes to behavioural standards 🙂
