Anyone with a proper range of skills will tend to be found outside of the jurisdiction of a CSCS site.
Given the iq of the average bricklayer or digger driver, I’d say there’s a good case for keeping them away from anything else.
the whole system is f***ed. New builds are throw together by monkeys who couldn’t care less, and our economy relies upon people enslaving themselves for thirty years to buy one.
Pricework is the biggest cause of s**t work, although to be fair the clowns that are there on day work aren't much better. Problem is with the speed they want them building, alot of large companies will just take anyone with a CSCS card to do whatever the job is. The cards don't really mean anything except someone has paid for the course/test and more than likely being led/prompted for the answers due to the trainer's not getting paid or bonuses.
Have seen some truly shocking work on site (don't go on very often) walls starting with a 128mm cavity then being 100mm by top of door opening, steels being fitted to find out the whole house is a course out from each opening, brickwork that steps in as it's out of plumb, let alone when down/uplighters are fitted that the wall looks like a game of Jenga, the chippies aren't much better and have even heard the plasterers say just easifill and sand the wall and that was in a brand new building
