Increasing time sovereignty is giving greater freedom to organize one's own use of time. This can be in relation to work, private life, education or any other form or combination of human activity.
Increasing time sovereignty in work could mean: (1) Counteracting negative forms of working-time flexibility (Sunday and night work, excessively long working days, summons contracts and contracts with strongly varying working time, etc.); (2) Increasing self-selected and individual shorter working hours, covering, among other things, leaves besides annual holidays (educational leaves, short-term leaves for personal or family reasons, etc.), possibilities for part-time work on a voluntary basis, and shortening or interrupting one's career at one's own initiative (parental leave, flexible retirement, option early retirement); (3) Increasing self-governed division of time, meaning greater collective participation of workers in their working and holiday times (alternative options for the collective holiday closures, extension of flexitime, free choice of periods of rest to balance overtime, etc).
Time sovereignty should be for those who want it and can demonstrate responsibility; it is not a right. Many people are unable to manage time themselves and need external structuring.
