We don’t seem to have the unofficial mentoring of old. If I see my FO doing something that is technically ok but could be improved with a bit of thought and the benefit of experience I’m not likely to tell him or her because it may not be well received. It’s likely to be met with argument for the technique they displayed. Only twenty years ago if I was informed of a different way to approach something I always took it onboard for consideration before implementing or discarding it. I certainly didn’t argue my position right off the bat.
There are no doubt benefits and pitfalls to both attitudes but I sometimes wonder how the new FO’s will ever progress if that mentoring is rarely occurring now days.
