This refers to an arrangement in which employees specify the days and/or hours they can work, and are scheduled accordingly, e.g. some caregivers of school-going children may opt to work specific hours in the day, i.e. 3-4 hours in the morning or afternoon while the children are at school, or during weekends when other caregivers are available.

This work arrangement may overlap with part-time work and/or job sharing, e.g. two or more bank tellers, cashiers, check-out counter staff share one full-time position throughout the workweek.
