I went for a job interview last year for a local council contract. The job was advertising for a tiler. When I went for the interview they wanted someone who could tile/plumb and basically do general maintenance. The council in question was Slough, and the maintenance is outsourced by Interserve. The recruitment is outsourced to Hays. Basically, nobody knows what is going on there. I had a lucky escape.
I did some work for a housing association referb last year as a tiler. I was asked not to do any prep of the walls. I was asked to tile over old adhesive & wallpaper. There was no setting out, and I was asked to grout wall tiles in the same day.
