Things did change, I have been with the same employer (in a half-dozen different position climbing the ladder) and I track the "progress".

I am a technology worker, and what I see is that in that sector self-training is becoming crucial.

Even when you start with a degree that only represent a fraction of the skill set demanded by your employer.

Even when the employer provides "training opportunities" you still need to compliment that with you own path to grow, which is very likely to be different from what you do today.

There are a number of "even when" and you only recognize them when you are already a veteran.

Once you are a veteran in any industry - all industries welcome you with open arms knowing you are capable to master your domain. But, you must prove yourself first.
