I think it varies widely from company to company.
And from country to country in my experience. Age, culture, ethics, the field in which they are engaged.........?
And, I'm sure, a host of other factors too.
A couple of examples if I may be permitted.
We, myself and a mechanical engineer, arrived on site in the far east. This was for the erection and commissioning of a paper machine. It was a Sunday and we were jet lagged but we agreed to take a walk round the mill. They had built a concrete motor plinth about 8x3x3 feet.
"What's that for?" I asked.
"The crawl generator."
"Um, we won't need that now," I said in passing
Next morning, there it was completely gone. Raised to the floor. I couldn't believe it.....
By way of contrast, I found your neighbours to the north to be the most unhelpful bunch I have ever worked with. Maybe it was just in that sector - naval dockyards.
Era and quality? I suppose many are of the mentality "you just can't get good staff these days".
There may be a ring of truth in that - at least here in UK. I put that down to two main reasons. Engineering as a profession is not held in high regard and most people don't have a clue about what it involves. "Working with tools and getting your hands dirty" is how one girl who was enrolling in a posh expensive finishing school. Fair made me spit feathers, that did.
The other reason is that, like most sciences, it is perceived as a "hard" degree. To get a not very sexy job.
