How much notice must be given for a change in scheduled duty?

The requirement for a change in scheduled duty typically reflects the standards set in labor regulations or company policies, which often dictate reasonable notice periods to ensure that employees can adequately prepare for changes in their work schedules. Providing at least 2 hours of notice allows employees enough time to adjust their plans, mitigating potential disruptions in their personal lives or family obligations. This timeframe strikes a balance between the employer's need to adapt to changing operational requirements and the employee's right to fair treatment and consideration regarding their work-life balance.
