Im a brickie. I can also class myself as a 'builder' too though as i am skilled in many other areas, especially joinery.
As for the CIS card i couldnt give two shits TBH. I am on the books and i prefer it. Dont have to fook about going firm to firm, dont have to go looking for starts when it looks like a jobs coming to an end, dont have to do any books etc etc
Im on price and earn as much as any other bricklayer on the cis, and gauranteed work through winter doing fook all and getting paid even if its a foot deep in snow, as long as i turn up....
Being on the books has a lot more advantages, holiday pay is another...
