“Tell me what I can do to help” always sounds dismissive when coming from colleagues and leaders. I interpret it as “I’m not going to understand this well enough to see my role.” If it fails, the leader can claim, "I would have helped but you did not ask" or "I did everythng they asked."
When leaders have no idea what potential is in their organization, those who can make the greatest contribution withdraw from the work... some leave, some “do their job” but nothing more, some contribute but their ideas are dismissed by those leaders.
