I work in a division that has 6 different departments. At the start of last fiscal year we moved from department dedicated admins to an administrative pool concept. Half were unsure and resistant, the other half supportive. One of those parties has since moved on, finding work elsewhere. The other still says a year later that she's unsure of how the pool works despite twice weekly meetings. There will always be someone not willing to join the team at the place where they are. I focus on team organization with Trello and emphasize cross-training on every task we perform, small or large.
