For many years I have been bemused by the British habit of labelling the people we would call Technicians as "Engineers".
Equally strange,is the habit in some countries of labelling non technical Operators,as"Technicians".
I am a "Technical Officer",or at least,I did a course,passed exams,got a Certificate,& worked as such.
Before I did that,I trained to be a Technician--did courses,passed exams,got a Certificate,etc.
I also have a "Broadcast Operator's Certificate of Proficiency" granted to me by the Commonwealth of Australia in all its awesome majesty,
This last,from its title sounds like it qualifies me to be a button pusher,but no! It is at about the same technical level as the Tech Officer's qualification.-----such are the vagaries of nomenclature!
None of those bits of paper are required for any job anymore,but they did at the time,& I would not have them without many hours of formal education,albeit not at Degree level.
Obviously,this also entailed a lot of home study,but I can't claim to be "self-taught"!
I just think of myself as a Tech,but in my last job,they wanted to call me an Engineer.
I said:-"Call me a Tech Officer if you want,but I'm not an Engineer,I don't have a Degree".
It didn't matter much until they needed to replace me.
Their ad (for an Engineer),brought in a flood of young Graduates who to be brutal,were useless for the job.
Really nice guys,& smart,but they would be wasting their time,& more to the point,ours!
They put it on the back burner,until I whinged a bit more about retirement,& this time they asked for a Tech/Tech Officer.
We still got a few hopeful EE Graduates,but a lot more people who might actually be able to do the job.
In most of the jobs where we had real Engineers,the boundaries were pretty much blurred as far as the type of work done by Engineers & Techs.
Either or both were at times testing equipment,designing stuff,climbing towers.or acting as an Electrician's offsider.
