If someone is moved around frequently - doing the same kind of role but e.g. in a different team and the roles they are moved into are always problem roles such as they are temporarily or permanently vacant at short notice, or there's some kind of failing in that team, how would you interpret this?
These are management level roles and it's not really standard in this type of company or the sector for people in these roles to be moved around.
Is it because this person has been identified as capable and a problem solver? Or has this person been identified as a mug who is capable of getting on with the task in hand and won't complain?
Perhaps this person would like a bit of consistency and security? Why does the business not consider this and what does it say about them that they don't?
