Internal Transfer: A Mixed Bag of Good and Bad
My views are maintained in the same order as your questions.
A transfer is always a mixed bag of GOOD and BAD.
1.0 Come to the GOOD first: new environment, new boss (may be a better boss), new place (better weather), new subordinates (may be better colleagues), new learnings, etc.
2.0 BAD aspects: new environment (tougher), new boss (may be a bad boss), new place (language difficulty), new subordinates (may be bad work culture), etc.
Eventually, you can make this also good. It will increase your patience, hone your behavioral skills, provide an opportunity to learn a new language, etc.
3.0 Beneficiary: Management (because it wants), Employee (since he uses the chance), Both (possible).
4.0 Loser: Management (the individual would get richer in experience and may move out), Employee (if he has been separated from his family), Both (when an employee cannot perform in the new environment).
So there you are. There are many possibilities, and you have to consider case by case and cannot generalize.
