basically the NASC is just a advisory body who have come on the outside and took over,i started scaffolding in 1963 (guess my age) them days you where graded by your peers (IE) fellow scaffs ,when you worked in a squad you had a top hand, fixer and labourer,you worked your way through for a couple of yrs and went for your trainee card via the union,worked for another couple of yrs then went for your second card (fIXER) and so on,this system worked very well ,in 1976 went offshore for Palmec (PALMERS) a few yrs later we where told we had to gget a citb card no one had heard of them ,bearing in mind by this time i had been in the scaffolding industry for15yrs ,having worked overseas ,and now offshore ,the offshore work was a lot different them days, if you did not hack it it was by by,Shell whose platform we where on kicked up a stink, needlessly to say we got what yrs later was classed as a grandads card ,but whatever ,i carried on working offshore till the mid 90s till it became a joke,i took a look at the scaffolding industry and some of the people that where now running the jobs and decided enough was enough, done a nebosh never looked back,what i am saying regarding the now ecitb cards they came out in the early 80s no reason why or what for just pay four pounds and your company paid four pounds for then a eitb card which was a black trade card ie engingneering background ,you then had the transport and general workers running a scaffolding card scheme you had a sitution where a lot of scaffs where double barreled card holders so they could have the chance to get a job, wherever there is a chance for any organisation to pick a working mans pockets legally someone will come along and gloss over the main issue not if your cabable of doing the job only if you can figure out who or what critirea the scaffolding industry is run by.
