Sorry have to disagree with some of that, many jobs have the safety of other in their hands..the electrical trade is no different than a bricklayer or a carpenter they all need to do their work to a more or less reasonable standard so it doesn't fall down and clobber someone.
The difference seems to be that for some misconceived reason the sparks seem to require some sort of heavy policing[/QUOTE]
This is,and always was,due to that inevitable driver, of money. Any war,legislation,onerous sentencing,or direct government involvement,is only generated by one thing,cost.
The technical trades,which were usually restricted by the nature of their required higher academic input,were generally at the higher end of the pay scale. This meant that the people benefitting,whether the employed or the employers,had sufficient "fat",to be skimmed off,in the name of safety or regulation.
There are no governing bodies,schemes or regulation,for leaflet droppers or car washers. No disrespect intended.
There are several reasons to believe that the scheme system,was more related to tax gathering,as any safety concerns,and nothing that has happened since it's inception,has convinced me otherwise.
Indeed,a great many topics covered on this forum,regarding new entrants to the domestic job,and recently completed work,of a sub-standard,would suggest a distinct lack of "heavy policing",or any redress or monitoring whatsoever.
It is,what it is...and we groove on
