What happens if employee takes leave on public holiday in Odoo 18?

Depends on time-off type configuration Public Holiday Included setting. If enabled employee requesting Dec 24-26 leave spanning Christmas Dec 25 consumes 3 leave days including holiday. If disabled same request consumes 2 leave days excluding Christmas. System generates separate timesheet entries: validated leave days create entries under configured leave task, public holiday creates separate entry under public holiday task. Both appear employee timesheet ensuring complete time tracking. Leave balance deduction follows Public Holiday Included setting providing flexibility managing different leave types policies supporting accurate leave accounting.

Can mandatory days be configured per department in Odoo 18?

Current Odoo 18 implementation applies mandatory days company-wide across all employees. Workaround for department-specific restrictions: create separate companies per department use company field mandatory day configuration, or use custom development adding department field mandatory day model filtering leave request validation logic. Alternative approach: configure time-off type approval workflows where specific approvers (department managers) reject leave requests critical department-specific dates. While not automated prevention provides control ensuring critical business days adequate coverage through approval process management oversight.

Public Holiday Inclusion Feature

Managing holidays within leave duration:

Understanding the Feature:

Odoo 18 introduces "Public Holiday Included" checkbox in Time-Off Type configuration controlling whether public holidays counted within leave duration.

Use for: Paid vacation, sick leave, personal leave

When Disabled (Unchecked):

Public holidays excluded from leave count
Example: 5-day request Dec 24-30 (includes Dec 25 Christmas) = 4 leave days consumed
Use for: Unpaid leave, leave-without-pay

Configuration Example:

Paid Vacation Leave Type:

Display Name: Annual Paid Vacation
Approval: By Employee's Approver
Public Holiday Included: ✓ Checked
Rationale: Employee entitled paid holiday, should count toward annual leave balance

Unpaid Leave Type:

Display Name: Leave Without Pay

Public Holiday Included: ☐ Unchecked
Rationale: Company already providing paid holiday, shouldn't double-count unpaid leave

Best Practices

Create Dedicated Internal Project for Time-Off Allocation: Mixing time-off entries with client project timesheets equals cost confusion budget inaccuracies. Create separate project "Internal Time" "Non-Billable Time" containing tasks Paid Leave Sick Leave Public Holiday. Ensures clean separation billable non-billable hours enabling accurate project profitability analysis maintaining clear cost allocation reducing reporting complexity improving financial transparency.

Configure Appropriate Approval Workflows Preventing Abuse: No validation time-off types equals employees self-approving extended leave insufficient coverage. Implement approval requirements: annual vacation requires manager approval, sick leave beyond 3 days requires HR officer validation, extended leave both approvals. Approval workflows maintain staffing levels prevent leave abuse ensure business continuity enabling proper resource planning building accountability culture.

Use Public Holiday Inclusion Setting Strategically per Leave Type: Inconsistent holiday counting equals employee confusion leave balance errors. Enable "Public Holiday Included" paid vacation leave types (employee consuming leave entitlement), disable unpaid leave comp-time (avoiding double-counting holidays). Clear policies consistent application prevents disputes maintains accurate leave balances ensures fair treatment enabling transparent leave management reducing administrative questions.

Leverage Calendar View for Team Coverage Planning: Approving leave requests without checking team availability equals understaffing project delays. Before approving requests open calendar view check overlapping absences verify minimum staffing levels maintained critical project phases covered. Visual planning prevents coverage gaps maintains service levels enables proactive resource allocation improving project delivery supporting business continuity.
