Leave

Leave types, accrual, balances, requests, and the multi-step approval chain with the Recommend (escalate) action.

• Leave types per org (CL · SL · EL · half-day · sandwich · maternity · custom)
• Accrual rules + balance ledger (every change immutably tracked)
• Requests with attachments + approval chain — Approve / Reject / Recommend (escalate)
• Threshold-driven escalation via policy engine (e.g. BM approves up to 2 days, AM beyond)
• Calendar view per team + clash detection
• Holiday calendar + weekly offs · location-specific overrides
