It's all 'horses for courses'. I'm in my mid 60's now. I've been an Electrician, special class, & technician
for 45 years in commercial/industrial environments. Through MOST of that, I had something to offer !!
Some people like to make themselves indispensable to 'protect' their jobs. I, on the other-hand, LOVED
to share knowledge, as I remember what it was like when first starting. Be-it Apprentices, or Work-
Experience people, or new tradespeople/techs. in various fields/companies. I NEVER withheld info !!
I'm talking about the days when the most learned/capable main-stayers in companies, knew every
inch of the Plant, and worked with PRIDE. And they were VALUED.
Throughout the majority of 'those' times, large companies also had teams of 'Carpenters', 'Welders',
'Plumbers' etc, as WELL as the ubiquitous mechanical-fitters/machinists and Elect/Techs....
NOW... it's down to outside Contractors/Sub-Contractors for 90% of all the work, or more....
OK,so where does this leave us
? (Let's digress for a minute).
I do not know about other countries, but here in Australia, most automated/specialized machinery
is now of a fairly standardized form, from many parts of Europe. The companies that supply the
machinery, also now have major contracts to maintain them, along with a lot of ancillary equipment.
I've repeatedly seen specialized 'techs' from a supplier, that know nothing about the individual plant,
and are starting from square one to find faults or work on the 'plant' as a whole.
Now I understand completely that times are a bit different now with regard to specific technological
advances, beyond 'Old-School' schooling these days, but PLEASE do not forget the absolute wealth
of knowledge that 'us oldies' can pass on for free, in a typical work environment. There's an old
saying about NOT throwing the baby out with the bath water !!! Most companies have done that
