Engagement is important. Research from ADP Research in 2018 of 1000 full-time employees in 19 different countries clearly indicates that employer engagement is determined by experiences someone has on a team level. Workers who say they are on a team are 2.3 times more likely to be fully engaged than those who are not.
All change starts with a loss
When starting any kind of change effort we tend to focus our attention on the destination or outcome that we (hope) to achieve when we are done. Change itself is situational; it is the external event that is taking place, a new strategy, a change in leadership, a merger or a new product. This is often in response to external events. It can happen very quickly.
