In our team everyone staff can work in place of others [when they are absent due to sickness or leave, usually staff at the same department/division. They just have to work more.]. And ready to help the team achieve its objectives.
We use a change of mind from the first glance that we have nothing to do, then do it gradually, step by step. And manage the day-to-day.
If there are issues that we need to coordinate with the team immediately. For it to work successfully.
