Which of the following groups has guaranteed hours?

The group that has guaranteed hours is composed of Regular government employees. Regular employees have established positions with a defined work schedule, which provides them guaranteed hours per week, as they are typically full-time employees with ongoing contracts.

Casual employees, in contrast, do not have a consistent schedule and are often called upon as needed, meaning their hours can vary significantly based on operational demands. Conversely, temporary staff also generally lack guaranteed hours as their employment is usually short-term and contingent upon specific projects or timeframes.

Considering this context, Regular government employees stand out as the group with consistent guaranteed hours, while Casual and Temporary employees do not enjoy such stability in their scheduling.
