I've recently been successful in an internal training programme in my workplace, where if after three years I can pass some exams and get signed off, I will be promoted three grades above my current grade.
I've been placed on a team that has decades of experience doing the job and due to the specialist nature, a lot of their knowledge is not documented per se but has built up over those years.
The basics are documented and my exams are based on the basics which I have grasped but I'm finding it difficult to move to the next level. While my colleagues are pleasant, there is some resentment that I will be a couple of grades above them when I finish and may well manage them, so they are not always eager to help.
Are there any ways of dealing with situations like these? How do I learn from people who are not overly willing to share their knowledge?
Additionally, are there any clever methods of recording what I do learn so I can really embed that knowledge, instead of hoping situations repeat themselves and I learn that way?
